|GSHHS||89.9 MB||Global Self-consistent, Hierarchical, High-resolution Shoreline (GSHHS) Database more...
The GSHHS dataset produced by the National Oceanic and Atmospheric Administration (NOAA) includes 20 shapefiles. This data comes in five levels of generalization: full, high, intermediate, low, and coarse. For each level of resolution, there are four types of content: land, lakes, islands in lakes, and ponds on islands in lakes. Although there is a dataset for the last type of data, ponds on islands in lakes, when you download it from NOAA, it is empty for the coarsest level of detail. This makes sense since the features are too small to show at the coarsest level of detail.
We did some processing of the GSHHS data. We eliminated some slivers along the 180-degree longitude, edited out some slivers in the Antarctic region, and used the Repair Geometry geoprocessing tool to delete any features with null geometry. We also created an additional set of feature classes (in the Level1_Processed feature dataset) that includes polygons for both the land and water areas for the Type 1 data (land). We created these using the Union function with the GSHHS polygons and a polygon representing the extent of global coverage (that we created by dissolving the World30 dataset on the Esri Data & Maps DVD) as the inputs. The advantage is that you can use this dataset to symbolize land, water, or both.
To help you, we have posted the GSHHS data here on the Mapping Center website's GIS Data page so you can download it easily. We also posted the data we processed. All this data is in a file geodatabase with six feature datasets, one for each of the five levels of detai, and a sixth feature dataset, Esri_Processed_Data, that contains the data we processed for all but the most detailed level of GSHHS data. In all, there are 24 feature classes (including one empty one) that you can use to make your maps.
|Hydrographic Flowlines||2.7 MB||This dataset includes hydrographic flowlines for the continental US. These flowlines were derived from the NHDPlus dataset created by Horizon Systems for the US Geological Society (USGS) and Environmental Protection Agency (EPA). One valuable aspect of this dataset is that the hydro flowlines have attributes, including two for mean annual flow.|
|Aspect-Slope Map and Data for Crater Lake||74.1 MB||This dataset contains elevation data for Crater Lake to create an aspect-slope map.|
|Crater Lake Elevation Data||36.7 MB||This dataset contains elevation data for Crater Lake for hillshading and layer tinting.|
|Crater Lake Bump Map Data||9.6 MB||This dataset contains elevation data for Crater Lake for bump mapping.|
|Crater Lake Final Bump Map||13.7 MB||This dataset contains the bump map data for Crater Lake.|
|Named Marine Water Bodies||3.7 MB||This dataset contains marine water body features for the world, but it does not include interior water body features.|
|Physiographic Features||2.3 MB||This dataset contains physiographic features that can be used for labeling a map.|
