Sometimes you feel like a nut, sometimes you don't!

Sometimes blogger links, other times it doesn't...please cut and paste above link.

UWF's Applications in GIS Unit 9 lesson plan centered on data management. We were to learn new methods or ways to organize your data for large projects and data sets. With all the problems I had with drive space this week, I lost focus and really did not come away with any new insight on data organization. I hope to complete lesson 10 and the Remote Sensing deliverable with enough time to review it again. (Ha--just like that reserving space last month Sue -- there is just never enough time in a day...)

I did learn that GIS in the real world will involve data sets and files that are computer resource hogs....patience and perseverance are key! A two computer system is very helpful and the ability to multi-task while you wait, essential.

I am very excited about the exercise this week. This area of Colorado is more like my own backyard (well not NORAD) than Florida where I currently live. I spent many years living in Colorado Springs and also a small mining community just on the western edges of our boundary area in Teller County. I worked all over of area of interest...in the cities, on the top of Pikes Peak and in little communities in the middle of nowhere.

I recently purchased copies and originals of several hand drawn and historical maps of the Cripple Creek and Victor Gold Mining District. Pretty cool stuff! There is a catacomb of gold mining tunnels (now managed by the CC/V Gold Mining Company) that span the distance between the two towns and who knows how far under the Front Range (toward Pikes Peak and Cheyenne Mountain).

One of the best maps I have ever seen is located in the Cripple Creek Museum. The map is enclosed in a glass box and raised up on a platform. You walk up several steps to view into the map from the top. Here you see a classic 2D map layout with different points showing the location of the mine entrances and camps or lines for trails and railroad. When you step back down you look into the map from the sides to see the different layers and levels of tunnels than run miles and miles deep into the Earth. Like I said, pretty cool stuff! I aspire to digitize, add attribute data and document the maps I purchased into a GIS to produce an historical overview of the mining activities of the area. Maybe someday I can compare them to the one at the museum. Yeah, Sue dreams BIG!

Palm Beach County Site Analysis by Sue Ritt

Palm Beach County is the largest county in the state of Florida in area. As of 2008, the rapidly-growing county's estimated population was 1,294,654. Palm Beach County borders Martin County to the North, the Atlantic Ocean to the East, Broward County to the South, Hendry County to the West, and extends into Lake Okeechobee in the Northwest, where it borders Okeechobee County and Glades County at one point in the center of the lake.

With wealthy coastal towns such as Palm Beach, Jupiter, Manalapan, and Boca Raton within its limits, as well as equestrian mecca Wellington and golfing haven Palm Beach Gardens, Palm Beach County is Florida's wealthiest county, with a per capita personal income of $44,518 as of 2004.

Mr. and Mrs. Smith, an affluent, established professional couple are relocating to Palm Beach County (PBC) and wish to purchase a new home in an upscale area that has a high percentage of children under the age of 18 and is also close to both their jobs. He will be teaching classes at Florida Atlantic University and she will be practicing medicine at West Boca Medical Center.

06.23.10 Deliverables Location Analysis

reserving space I will catch up here soon...

06.09.10 Deliverable #2

The first of three submissions analyzing the impact of the Deep Horizon Oil Spill in the Gulf of Mexico in the Fort Barrancas, Florida area (ESI Map Index Tile 5).



Sean's gracious comment below refers to an earlier map I posted to test the view of my topo layer.

05 June 2010

06.09.10 Deliverable #1

This map was created as part of UWF's Applications in GIS class Unit 4 class project deliverable one: Deep Horizon Oil Spill; Fishing Closure Boundaries. Longitude and Latitude coordinates were obtained from existing NOAA maps, input into excel and imported into ArcMap. We created a new polygon shapefile, started an editing session to create the boundary layer from the imported point file and then exported the boundary file as a kml file. My first go round my kml file put me on the NW corner of the Galapagos Island. Upon reopening the mxd file, I noticed one of my coordinates was along the equator. I deleted the files and started over.

06.02.10 Deliverable #5

The Mississippi Coastal Counties Hurricane Katrina Flood Water Extent Map was made for the University of West Florida's Applications in GIS class project for Unit 3: Hurricane Analysis. Initially students were required to present a layout view map showing elevation, hydrography, and Bathymetry of the Mississippi Coast counties with places, types of water, barrier islands, and hydrography. By adding the US Geological Survey land cover file and reclassifing land cover types into 7 catagories, students were then directed to submit a graph detailing flooded areas by land cover type. Finally, we were asked to create a table detailing the land cover types affected by the storm surge expressed as a percentage, by acreage totals per land type and by square miles.


06.02.10 Deliverable #4

The Coastal Mississippi Counties Hurricane Katrina Infrastructure Damage Assessment Map was created as the fourth deliverable for UWF's Applications in GIS class project Unit 3: Hurricane Analysis. The map details the roads, hospitals and churches most likely to be flooded from Hurricane Katrina's storm surge.

Central southern Harrison county should experience the least amount of flooding with southwest Hancock and eastern Jackson as the hardest hit areas. Singing River Hospital, Hancock General and Hancock Medical Center lie directly in the flood zone. Ocean Springs, Gulfport Memorial or Sand Hill Hosptials may be better positioned to remain in operation. In addition, most coastal churches will be impacted by the storm surge so shelters should be opened in the northern portions of the counties.

Travelers in Hancock County along US 10 will find impassable flooded roads therefore highway ramps have also been included in the map to assist EOC with rescue efforts.A small portion of western and northern county road 607 should remain passable for emergency vehicles. Similiarly, only the western portions of US 10 and CR 90 will be passable in Jackson county.

06.02.10 Deliverable #2 and 3

The Mississippi Coastal Counties Hurricane Katrina Flood Water Extent Map was made for the University of West Florida's Applications in GIS class project for Unit 3: Hurricane Analysis. Students are required to present a layout view map showing elevation, hydrography, and Bathymetry of the Mississippi Coast counties with places, types of water, barrier islands, and hydrography. We were then required to submit a graph detailing flooded areas by land cover type.

Taking our map one step further we added the US Geological Survey land cover map and reclassified land cover types into 7 catagories.

Problem:

The catagories listed in Step 5 substep 4: 0 not flooded; 1 water; 2 barren; 3 developed; 4 forest; 5 agriculture; 6 wetlands; DO NOT MATCH the catagories provided in previous step 3 reclassifity land cover substep 3. As a result, I think the map is an inaccurate assessment of flooded lands. Given I followed the instructions precicely and I do not have the time to fix the error, I am moving on.

06.02.10 Deliverable #1

The Mississippi Coastal Counties Elevation and Hydrography Map was made for the University of West Florida's Applications in GIS class project for Unit 3: Hurricane Analysis. Students are required to present a layout view map showing elevation, hydrography, and Bathymetry of the Mississippi Coast counties with places, types of water, barrier islands, and hydrography.

The area's high ground tops outs at 103 meters or 338 feet above sea level. Unfortunately, a small percentage of the coastal counties of Hancock, Harrison and Jackson, Mississippi sit at this elevation. Instead, elevations up to almost 8 meters or 26 feet below sea level dominate. As is common along all of the United States shorelines, densly populated communities are found in these low-lying areas. Also present is a vast hydrographic system with thousands of creeks, rivers and swamps.

Problems:

1. Following this Step:
12. Add water and symbolize it with Unique Values using the FTYPE field. For the sake of time, remove all values except Swamp/Marsh and symbolize with a distinct color or symbol. To remove values, right‐click on the type under .

I was not able to remove the values as indicated in this step. I'm not following how to right click and remove the value. Instead I created a new shape file of the wetlands and swamps using select by attribute.

2. The slanted raster image AND slanted map. I do not undersand how I would crop this so that the pic is a square rather than slanted. I tried cropping it, I tried changing scale and also tried to enable the clip image in data frame properties.


As usual feedback and suggestions are greatly appreciated! Thanks! Sue

Spring Break Deliverable


This lesson was relatively fun and easy. Since the TIITF parcels are held in trust for the public I groups these all together. I wanted to use the raw data from the website but the tax roll file did not contain the acre data and I am not so good a math calculations so I went with the file UWF provided instead. How do you think I did?

030310_Deliverable



This lesson taught us how to modify the features that exist in maps and also how to add features into a map by digitizing. Like all my other labs I ended up doing the task several times before I got a result I was satified with. I donot like how the roads and building extend off the edge but could not clip them. I was not sure which feature to clip from and building roads and athletic fields were my only selections.

02.23.10_Deliverable_Finally!



Better late than never! After a few attempts I got the raster to line up after the second control point. From there the exercise was fun and the northern part of the image was relatively easy. My RMS for the upper portion is 14.9. As you can see I had a bit of trouble with the southern part. My pic image warped (see the left side bending in?) and the road on the west did not line up correctly. I used a 3rd order transformation with an RMS error of 17.86382. I tried to compensate for the warping with my legend. I would have liked to had a black rectangle to format the legend and brought forward all the pertinent information into the boundary box but could not remember how to get there. Tips, feedback and suggestions are greatly appreciated!

This is a map of Flagler County, Florida, U.S.A. What do you think?


Wow! What a lab project this was and I still have to find and prepare my raster map. Oh boy!

Things I learned:






  1. Do not reorganize your H drive while still creating maps. This results in map drawing errors as ArcMap cannot locate the original link. I started over many, many, too many times as a result to trying to get my files organized. Also on this topic, the H drive should be well organized and labeled for each lesson. I wanted to insert files from previous lessons and spent quite a bit if time navigating the R drive to locate what I needed to copy again.



  2. Arc Catalog is a great tool! After I lost my links on my first, second and third maps I decided to make sure my files were not corrupt and all located in the same place, so I deleted all the unzipped, reprojected and clipped files I had used to date. I then unzipped again (into my nicely organized file) and used Arc Catalog to reproject and clip before I even dumped the files into ArcMap. What a time saver!!



  3. I finally figured out the fixed scale option which eased quite a bit of my frustration and I exported as a .png file at a 125 resolution. I don't know what any of that means but it was suggested and seems to have increased my map size considerably.



  4. I learned that I have forgotten how to add the little red box (area of detail) so I added a neat line and reduced the box size as small as I could.



  5. I wanted to move some of the icons off the coastal areas so they did appear over the county boundary but was not sure how to accomplish this.



  6. Also, I could not figure out how to add the ocean to the map.



Please let me know what you think! I appreciate any feedback!

This map shows the population migration out of the devastated city of Port-Au-Prince. Since this map represents where the people have moved to relief operations, police and government officals will know where to direct relief efforts.



02.10.10 Deliverable #1


I really liked the repetitive tasks in this exercise. I am a firm believer that when learning software, you either, "use it or lose it" and the more I repeat a task the greater chance I will have to remember it. Three maps in one exercise is great!

This lesson required we analyze the differences in Florida county boundary layers using three different coordinate systems; Albers, Universal Transverse Mercator and State Plane N. To redefine coordinate systems, we accessed the Project tool found in the Projections and Transformations toolset in the ArcMap Database Management Toolbox. To assist in the analysis of the maps, we also learned how to add a new field to an attribute table.

With the exception of Escambia County, the sq mile area totals in the UTM projection are higher than seen in the other two coordinate systems; however, the differences are slight with the largest variation of 19 square miles. Yet these differences in area emphasize the necessity of using the same coordinate system in each map layer. Layers with different coordinate systems will locate data in the wrong place.

Given the small variances in area, I wanted to try to make them stand out as much as possible so I decided to keep all the other variables in the three maps uniform and used the same background colors and fonts in all three maps. Well, at least I tried. I continue to struggle with uniform fonts and think the larger font on the Albers map make the polygons in this map falsely appear larger. I also wanted to present the area data within the polygons. To do this, I needed to use a scale that prevented the use of data frames or borders; otherwise, I could not fit all three maps on one page. Since my tired old eyes could not easily make out these numbers, I also included the chart.

Please provide feedback -- I really want to learn!!

Peace~Sue

02.03.10 Deliverable #3

With the color schemes I chose, I could not tell the difference between the stretched and classified symbology methods on the actual maps as I was working in ArcMap. Accessing the properties box did show me that the stretched method is based on standard deviation while the classified method breaks the data into classes based on natural breaks. Once I posted the maps side by side, I was able to see differences. On the maps with the green to white color plate, the classified map shows more detail as I was able to manipulate the number of classes to further detail changes in elevation at the upper levels. Once I changed the color scheme to one that used multiple hues instead of levels of saturation, the stretched symbology method presented details better.



























































































02.03.10 Deliverable #2

I had trouble with the annotation conversion for the city labels in this exercise. I think the TS lagtime might have played a role since I ended up with two or three different labels for each city. Again I saved, saved, saved so starting over was not as frustrating as in the last exercise.

Since we were not relating any other spatial information that required a change in my world countries layer color, I kept the brown from Exercise #1. Another change I made is to the color that represent railroads. My old eyes could not see those tiny tracks in the default symbol so I changed the color to fire red and moved the layer to below highways so it would not overwhelm the map.

What do you think?

02.03.10 Deliverable #1

No real problems with this except inexperience with the software. I wish ArcMap had an undo feature similar to that of MS Office products. One wrong click and I am starting all over. I also learned the importance of save, save, save.
I selected the yellow, orange, red color scheme to represent population data because the data is quantitative and the hue progression reflects the increase in population amounts.
Always a perfectionist, I also wish my city labels were cleaner and more legible. I wonder if there is a standard for placement of legend, scale and pointer? Should they be placed inside the map frame or should I re-size the map so these items are displayed along the borders?

27 January 2010

Deliverable #2 01.27.10


Well, I guess I should not do my labs so late at night or early in the morning! I missed the fact that I do not have a legend to specify what my colors represent. I am going to try to make the changes now. I hope it's not too late. SueB
--------------------------------------------------------------------------

The only problem I had with this exercise is that I could not find the coordinate display pointer to answer question #3. Can anyone help me with this?

A new problem just occurred when I went to create a new post. The blogger prompts me to change my existing post and I needed to delete my previous map in order to sumit this one. I can see from other posts that students were able to keep an archive of the older submission so I know I must be missing something basic.

Any assistance is appreciated!

01.16.10

The only problem I experienced during these two exercises was differentiating between the toolbars in Arc MAP. In the beginning I selected the Layout toolbar zoom icon rather than the other toolbar zoom icon. (What toolbar is that?)

As a result my map was different from the examples and I repeatedly closed out of Arc MAP to start over. (Very frustrated!) Until that is, the lesson on bookmarks was presented. I still did not dawn on me that there were two zoom icons to select from but at least I didn't have to shut down the program to start over on the map.
