Title: Locations of digital elevation model datasets in the SJRWMD

Geospatial_Data_Presentation_Form: vector digital data

Online_Linkage: <http://www.sjrwmd.com/gisdevelopment/docs/themes.html>

Description:

Abstract:

This layer contains the footprints of DEM datasets. Each feature corresponds to one dataset, and some of the features are mutlipart. Fields identify layer and SJR button names. Most of the datasets are based on lidar collections. NOTE: we do not redistribute all of these datasets (see the ExternalDist field in the layer). Some should be obtained from the originating county.

Purpose:

The purpose of this layer is to 1. depict which areas of the District are covered by digital elevation model datasets other than general Districtwide layers, 2. indicate what we are calling each dataset on the SJR button as well as the SDE layer name, and 3. whether or not we are redistributing it on our data download site.

Supplemental_Information:

Sources of information include GISLIB.TOPO_INDEX and the project area indexes for deliverables.

Attribute:

Attribute_Label: TYPE

Attribute_Definition:

Indicates whether the dataset is available as contours, a digital elevation model, or both.

Attribute:

Attribute_Label: NAME

Attribute_Definition:

The general name of the dataset. Name is consistent across data types - if contours and DEMs are present for the same project/data area, the layers will have the same Name, but different SJR_TOOLBAR_NAME and _LAYER names. It is also used to identify the dataset on the external data download page.
