GeoCue FAQs

GeoCue FAQs are some of the frequently asked questions about licensing, installation and workflows for the GeoCue Workflow Management product.

1. How can I update LAS Header Information within GeoCue?

GeoCue has a Utility Step called Update LAS File that is specifically designed to update the header of a LAS file. This utility step allows the user to update the LAS Version, the header fields for File Creation Date and System Identifier and the projection information. Update LAS File is generally run as a final step before delivering products.

2. Is there a way to import a point set from tabular data (spreadsheet with x and y columns) into GeoCue?

The best bet would be to import the tabular data through the Import Control function. The format of the data would need to include x, y and z values. If there are no known z values, a value of 0 can be used instead.

3. I have created dZ Orhtos for a set of tiles, however some of the Orthos display in Geocue and some don’t…All of the tiff’s are in the layers folder and I can view them when I open them separately ….Why does this happen and how to correct it without having to create a new set of Orthos?

The display of imagery in GeoCue may be controlled in a couple of different ways. In:
i) Layer Properties you may have the Always Load Images unchecked. If so, then you will need to select the images you wish to view, right-click and select load images
ii) In Layer Properties you may have the Raster Display Range set on the Zoom tab.In which case images will shut off once you have zoomed in or out too far.

Perhaps one of these settings is turned on and that is why some of the imagery doesn’t display.

4. How does one attempt to automate a process that merges .LAS files together with a max file size of 2GB?

GeoCue doesn’t have the ability to specify a file size limit when creating a tile layout, however, you can specify a desired number of points based on nominal point spacing. Of course, the number of points is directly related to the file size since there are a set number of bytes per point depending upon the LAS point data record format (PDRF) used so one could determine a desired number of points based upon your desired file size. This is done by creating a LAS_Boundary entity on an LAS_Working_Segment layer.
