GeoGateway
Contents
GeoGateway enables downloading shapefiles from web servers. Make maps from scratch. GeoGateway simplifies the download process, makes it faster and provides a more efficient way to integrate shapefiles and other GIS files into GIS projects.
GeoGateway includes two main features:
1 - download shapefiles and related data to a local computer using a menu-driven process
2 - optionally add the downloaded data to an existing or new project (forget the unzipping and related details)
MapBuilder. In combination, these features enable development of a GIS project focused on the geographic area and type of geography of interest.
Optionally integrate demographic-economic subject matter accessed via CV XE APIGateway and other CV XE resources.

Downloading a county by roads (edges) shapefile
Adding the downloaded shapefile as a layer in a new GIS Project
Start CV XE and Close the current project. Use File>GeoGateway to start GeoGateway processing.
Step 1 (with same GeoGateway form open) ... download the shapefile
Dbl-click Travis County, TX in listbox1; available shapefiles appear in listbox2.
Dbl-click EDGES shapefile in listbox2; the File to Download and SaveAs edit boxes are populated.
Clicking the Download button in the above view will:
| • | download the TIGER 2017 Travis County, TX roads/edges shapefile to the local folder specified in options settings |
| • | unzip the downloaded zip file to that same folder |
| • | delete the XML file |
| • | delete the downloaded zip file |
Delete operations are options settings.
The shapefile is then immediately ready for use.
Step 2 Add the downloaded shapefile to a GIS project (optional)
The Add Layer to Project button becomes active.
Select the Shape Label in the drop-down. Next click the Add Layer to Project as shown below.
Close the GeoGateway form. We could continue, but in this example the GeoGateway operations stop with one shapefile.
The map view now appears as shown below. Zoom-in to the pointer location in the Kansas City area.
The next view illustrates ZIP code areas/boundaries (red) with labels. The Identify tool is used to show a mini-profile of a selected ZIP code -- 64133 -- see pointer.
Related options now available include:
| • | Save the project and close CV XE (saving a project requires CV XE Level 1, 2 or 3; a project cannot be saved with Viewer) |
| • | Re-start GeoGateway and add other shapefiles to this project. |
| • | Close CV XE without saving the current project (downloaded shapefile remains on local computer). |
