Angelique's GIS Portfolio

For my final project I analyzed population sizes in known locations and habitat types occupied by the St. Andrews Beach Mouse ( Peromyscus polionotus peninsularis ) in Gulf County, Florida. In addition, I analyzed adjacent parcels within the St. Andrews Beach Mouse's (SABM) maximum dispersal distance. A detailed explanation of my analyses with map layouts can be found here: http://bit.ly/2XZuOTQ.  I performed GIS analyses in ArcGIS Pro on data collected from the FGDL Metadata Explorer website. I used the following tools in my analyses: Clip, Create New Feature, Calculate Geometry Attribute, Join, Multiple Ring Buffer, and Intersect. The GIS analyses of the St. Andrews Beach Mouse population in Gulf County, Florida are effective in showing the extent and types of habitat types occupied. The population sizes and dispersal patterns are also easily discernible and interpreted from the maps.   Spatial analysis indicates SABM occupies 28 miles of shoreline along two sm...

The purpose of this lab was to georeference unknown raster images of the UWF campus to known vector data, digitize new line and polygon features, create multiple ring buffers and overlay data in a 3D environment. To create the first map, I georeferenced two unknown rasters using the Control Points tool. For each raster, I created 10 control points, keepings the RMS error low. For the second raster, I used a 2nd order polynomial transformation for a better map appearance. I then digitized a new line feature for the new campus road and a new polygon feature for the new gym. Finally, I used the Multiple Ring Buffer tool to create a conservation buffer around the eagle's nest that corresponded to FWC requirements of 330 ft and 660 ft. The second map is a 3D overlay of the first map (without the eagle's nest). In order to create the 3D effect I used lidar data from USGS National Map Viewer. To convert the lidar to a DEM, I used the LAS Dataset to Raster tool. I then used the DE...

The objective of this lab was to geocode by address matching and complete a route analysis for EMS station locations in Lake County, FL. For the lab, I downloaded a 2017 US Census Bureau Tiger Line shapefile for Lake County, FL from their web interface. This data was projected to NAD 1983 Harn State Plane Florida East FIPS 0901 Feet using the Project tool. I then created an address locator using the Create Address Locator tool from the Geocoding toolbox. Using this address locator, I mapped or geocoded known EMA station locations from address and zip code. Thirteen of the addresses were matched but there were still 8 unmatched results. Two of the unmatched addresses had possible matches. In order to match the address, I added the street maps basemap and zoomed to the layer to check the matches against the street names and addresses. In order to match the remaining locations, I looked up the addresses in Google maps, found the largest nearby street, used Select by Attributes to locate...

The purpose of this week's lab was to explore the most common modeling tools in ArcGIS - buffer and overlay - and create a script in ArcPy for the buffer tool to combine or exclude multiple vector features. The resulting map includes final possible campsite areas, after applying the overlay tools.   First, I used the Buffer tool to create a feature class with a fixed distance. The resulting feature class included areas within 300 meters of roads, dissolving all buffer borders so that areas of overlap were merged.  Next, I created a feature class with a variable distance from the water features (150 m for lakes and 500 m for rivers). To do this, I added a field to the attribute table of the water feature that included the desired buffer distance for each feature type, and then I used the Buffer tool with these fields as the buffer distance and dissolve type. I also used ArcPy to create a script to use the Buffer tool to create feature classes with variab...

The purpose of this lab was to search for and select GIS data from multiple sources and create easy to interpret maps with the data for an assigned county in Florida. I was assigned Gulf County. The GIS data required for this lab was 1 Digital Orthographic Quarter Quadrangle (DOQQ) aerial, 1 Digital Elevation Model (DEM), 5 vector files representing the county boundary, cities & towns, roads, public lands, surface water (lakes and rivers), and 2 of 4 environmental vector files (I chose wetlands and invasive species). I found all vector files and the DEM by searching the Florida Geographic Data Library (FGDL). I found the DOQQ by searching for a quad in Gulf County under the aerial images section. The most difficult single layer to find was one for surface water. It was difficult to find one layer that showed both major rivers and lakes in Gulf County. Instead, I found and used 3 layers that accomplished this and looked the best on my maps.  Because all of the files...

The purpose of this lab was to find, import and reproject data into a common coordinate system:   NAD 1983 (2011) StatePlane Florida North FIPS 0903 (US Feet) .  The screen shot above shows the Map View from ArcGIS Pro with all the required data layers in the same coordinate system.  In order to find a quad number to search for aerials in Escambia County on Labins.org, I searched the FGDL.org site for a "quad index" to find the  qd24 data layer. I will note that Labins.org has a search tool to find quad numbers but it was not functioning during the time period for this lab.  I also used the site to find a county boundaries layer by searching for  "county boundaries."   Finally, I found a major roads data layer by searching for "major roads" on the site. For the roads, I chose a shapefile from the Florida Department of Transportation (FDOT) called majrds_jan19. Because all of these files were not in the correct coordinate system, I ad...

The purpose of this lab was to explore different coordinate projections. For the lab, I projected the counties of the state of Florida in three different coordinate systems: Albers, UTM 16 N and State Plane N. Upon visual inspection, the UTM and State Plane projections are slightly compacted and rotated counter clockwise when compared to the Albers projection.  In order to see how this visual difference impacts the physical characteristics of the counties, I selected four counties distributed throughout the state – Alachua, Escambia, Miami-Dade and Polk – and compared their area in square miles. There are differences in area between the three projections for all counties. The greatest differences in area are for the two largest counties – Miami-Dade and Polk. In addition, the UTM projection has the biggest area difference for Polk County. From this analysis, I conclude that the UTM and State Plane distort the areas of some counties more than others, especially larger c...

The purpose of this lab was to collect field data using ArcGIS Collector and then use the collected field data to explore several methods to create and share the resulting maps: ArcGIS Online map, story map, Google Earth KMZ web map and map package.  I chose to collect field data on fire hydrants on my running route. Before heading out to collect data, I created a new feature class with a custom attribute table and a "Condition" domain that included a list to assess the condition of the hydrants. I uploaded the feature class to ArcGIS Online and  created map. I downloaded the ArcGIS Collector on my phone and used it to survey the fire hydrants during my run. I found the ArcGIS Collector App easy to use. My domains were set up correctly and I could choose from the list I created. I was also surprised that the Date field automatically allowed selection from a scrolling list. I was worried that I would have to enter the date manually and I could see how that would create...

The purpose of this week's lab was to create 3 maps, alter symbology, explore labeling, and utilize dynamic text. The 3 maps each depicted different features of Mexico. The first illustrated and labeled the Mexican states and symbolized states into 6 groups by population size. The second included and inset map and illustrated urban areas in Central Mexico with railroads, major federal roads and major and primary rivers, each symbolized uniquely. The map above is the third map which shows to topography of Mexico, symbolizing a raster feature class with a color ramp. I chose the Surface color ramp because the Mexican elevation raster feature layer shows elevation. This color ramp represents high elevations as white and low elevations as green. Because high elevations are mountain tops which usually contain snow and low elevations are valleys which are usually green, the surface color ramp makes the most sense to represent these natural features. I also decided to no fill the Legend...

This is the second lab assignment for Introduction to GIS. The purpose of this lab was to become familiar with the Layout view in ArcGIS Pro and create a personalized map template with the UWF GIS Online essential map elements:  Title, Scale, Legend, North Arrow, Border, Date, Data Source, and Cartographer Name. In this way, I am developing the skills to "Own Your Map" and truly make it my own. The final product i s a map of the location of the University of West Florida’s (UWF) Main Campus within Escambia County. There is an inset map of the state of Florida, with Escambia in red, orienting the audience to its location within the state. Because Escambia County is longer than it is wide, I chose a portrait orientation. I used neutral background and fill colors for the inset map and legend so as not to distract from the main focus of the map – the location of the UWF campus. I attempted to match the Title colors and font with the UWF logo colors and font for consistency. ...

The purpose of the the first lab in Geographic Information Systems (GIS) was to explore some of the features and functions of ArcGIS Pro by working with and exploring an example data set and creating a map of world countries by populations with major cities. In addition, the lab introduced terms associated with GIS, applying them in the creation of the map. The lab included step-by-step instructions for creating the map, allowing students to make design choices for the essential map elements and layout. The image above is the resultant map I produced for the lab. I found the lab easy to follow and although this is not the first map I've created in ArcGIS Pro, it is the first map I've produced by myself in some time.
