The first step in most GIS enabled planning projects is to assemble a set of resource layers and maps. Typically, these layers can be broken down into two categories: natural resources, and human-made (built) resources. The following list describes the layers and maps I typically produce for various projects. Most projects do not include all of these layers, although comprehensive plans can sometimes come very close. The maps can be produced via traditional paper maps printed at various sizes, saved as PDF documents or digital images, or they can be displayed via a desktop or web-based viewing application . These digital solutions have the advantage of being able to combine and visualize the various layers in any combination the viewer wants.
Layers and maps we typically include in our projects
|Property Boundaries||Agriculture (Uses and Districts)|
|Hamlet Detail||Farmland (Uses and Soils)|
|Aerial Photos||Historic Sites|
|Topographic||Government Owned Land, Parks, and Recreation|
|Topography||Public and Protected Land|
|Watersheds||Special Districts (Water, Sewer, Lighting)|
|Water Features||Tax Exempt Properties|
|Flood Hazards||Land Use/Land Cover|
|Bedrock Geology||Empire Zone|
|Surficial Geology||Coastal Zone|
|Septic Limitations||Future Land Use (Conceptual Zoning Districts)|
|Depth to BedrockWater Table||Public/Committee Input|
|Drainage and Permeability||Workshop/Survey Map|
|Flood and Pond Frequently||Community Places|
The ability to produce these maps depends largely on the availability of the required GIS data. Some layers are more readily available than others. For example, mapping of aquifers will require the services of a hydro-geologist. Mapping of tax exempt properties will require extra time consulting with the local tax assessor. Special districts and infrastructure may require scanning and digitizing of hard-copy maps.
