Interpolation Methods – Tampa Bay Water Quality

There are numerous spatial interpolation methods used to generate surfaces in GIS. This is the prediction of variables at unmeasured locations based upon sampling of similar variables at known locations or true points. Related, spatial prediction is the estimation of variables at unsampled locations based partly on other variables and a collective set of measurements. Comprised of spatially continuous data, surfaces could be topographic, a measure of air pollution, soil moisture, air temperatures [...]

Searching for the right GIS job

Finally got started with my GIS Internship with the Florida Department of Transportation at District 7 (D7) Headquarters last week. The position affords me the opportunity to work on several GIS related tasks and with multiple departments. I am working with a great team and providing assistance to others with ArcGIS Pro. Settling into my internship position at D7 went very smoothly. My initial task is working on a [...]

3D Mapping – TINs and DEMs

Moving on from Spatial Data Quality in GIS Special Topics, the next Lab focuses on surfaces with a comparison of the Digital Elevation Model (DEM) and Triangular Irregular Network (TIN). A surface in GIS is a geographic phenomena represented as continuous data. Continuous spatial data references geographic objects characterized by very gradual boundaries such as temperature or elevation. The most common way to represent elevation data is with contour [...]

Spatial Data Quality – Road Network Completeness

Continuing the focus on Spatial Data Quality in GIS Special Topics, Module 1.3 covers the Accuracy Assessment of Roads. Road networks are widely used as the basemap for many applications. This factors into expectations for positional accuracy and completeness, which this week's lab covers. Road networks are also used for geocoding and network routing. The usability of such is dependent upon robust attributes such as street names, address numbers, [...]
