Elevation model
Prepare and symbolize a digital elevation model to reveal Brevard County's subtle relief while retaining roads, waterways, boundaries, and recognizable place context.

Brevard County elevation and land cover.Two environmental views of one landscape.
Paired cartographic products showing the county's physical relief and Landsat-derived land-cover classes within a consistent geographic context.

01 / CARTOGRAPHIC PRODUCTS
The finished maps
The full-size maps make the legends, reference geography, scale, and Florida locator easier to read than they are on the portfolio homepage.
02 / METHODS AND DATA
How I prepared the two raster products
I used the same county boundary, supporting geography, scale information, orientation, and Florida locator on both maps so readers can compare them easily.
Land-cover interpretation
Apply class-based symbology to Landsat-derived land-cover data so developed areas, forests, wetlands, agriculture, water, and other classes remain distinguishable.
Cartographic composition
Combine each analytical raster with a clear legend, scale bar, north arrow, source information, county outline, and statewide locator map.
03 / INTERPRETATION
Limits of the source data
The elevation map communicates patterns contained in the source DEM; its apparent precision depends on the resolution and accuracy of that dataset.
I interpreted and mapped an existing Landsat-derived classification product. I did not independently produce its classes from raw Landsat scenes.
04 / TEACHING APPLICATION
Using these maps to teach raster data and cartography
I would ask students to compare what each raster represents, examine how resolution and classification affect interpretation, and critique the legends, colors, scale, and locator map.
