6. Frequently Asked Questions

This is a list of Frequently Asked Questions about the Data Searches tool. Feel free to suggest new entries!

6.1. General questions

How do I get a copy of the tool?

The source code as well as the installer setups can be downloaded from GitHub (MapInfo or ArcGIS). Please ensure that you use the correct configuration file, examples copy of which are also included with the releases.

Can several people use the tool at the same time?

Any number of users can use the tool if they have a copy of the tool installed or loaded in their own copy of ArcGIS or MapInfo. The tool uses all data layers that are loaded in GIS in a read-only fashion, so there is no limit to the number of users of the tool. Where outputs are written to a central (network) location, it is important to ensure that no two users are running a search on the same search reference at the same time as this can lead to unexpected results.

Does the tool work with QGIS?

Currently only ArcGIS and MapInfo implementations of the tool exist. However, if funding was available the tool could be adapted to also support QGIS.

6.2. Operating the tool

One of the data layers I want to use isn’t showing in the form. How do I get it to show up?

This issue can arise in several ways:

  • The layer isn’t loaded in your GIS document or workspace. In this case, a message will pop up before the form is displayed informing you the layer isn’t loaded. Add the layer to GIS and restart the tool and the problem should be resolved.
  • The layer isn’t listed in the XML configuration document. Please refer to the setup section and add it as a map layer.
  • The map layer is listed in the configuration document, but the ‘LayerName’ is spelled incorrectly. Note that the name must follow the exact format of the name of the layer in the current GIS document or active workspace (in ArcGIS the name is also case sensitive).

I ran a data search twice with different radius settings. The combined sites table only has one set of results

When the same search reference is used twice, the combined sites table will be overwritten in the second search unless Append to existing table is selected in the ‘Create Combined Sites Table’ option. Please see the warning in the ‘Running the Tool’ section for details.

I ran a data search twice with different radius settings and included the same data layers. There is only one set of results

When the same search reference is used twice, the output from any layers that were also included in the first search will be overwritten. If you need to keep two sets of results, for example using different search radii, then move the results from the first search to a different folder before carrying out the second search.

6.3. Tool issues

How do I report a new bug or propose a change in the tool?

Please check the existing known issues and change requests on the LERCAutomation pages on GitHub (ArcGIS, MapInfo) before reporting/proposing new issues or changes. If you have a new issue or request you can submit it there and it will be picked up by the developers. Alternatively, you can email suggestions to Hester or Andy.
