Augusta Elevation Grid Using Scaled Model Parameters Values



 1) Light colored area is the USGS orthoimage. Download more data than you need to allow

    flexibility to adjust bounds and possibly avoid having to download more data if your map

    projection leaves some areas in the bounding box undefined.

2) Export the elevation grid using the GeoTIFF option. Image files deselected.

    Set the File Type as Elevation (32 bit floating point samples).

    Check "Export at Fixed Scale 1:" set the scale as 9600.

    Set the DPI value to save the image as: 100.

    Check "Interpolate to fill small gaps in data".

3) Select the 'Export Bounds' tab to set the export bounds. First draw a box encompassing your

    area of interest. This will establish the NW corner and an initial size.

    Select the 'Corner w/Size' Option.

    Enter 15 for Width and 10 for height for scaled model size.

    Manually change the the location of the NW corner to fine tune.

    Write down and save the NW corner location for later use in generating the IMAGE file.


4) Click OK at the bottom of the GeoTIFF Options window. The 'Save As' window opens.

    Name the file and append SHAPE and a sequence number:  AugustaSHAPE1x


    Click 'Save'.
