Converting ESRI .lpk files to Shapefiles for use in QGIS 2

Converting ESRI .lpk files to Shapefiles  for use in QGIS
ESRI ArcGIS can export compressed geographic files using the ‘LPK’ file extension.

New Maptitude Add-ins for Territories and Vehicle Routing

Caliper have just released two new add-ins for Maptitude: Balanced Territories Add-in This add-in automatically creates a new territory layer from an existing area layer.

Geospatial Data Verification

Geospatial Data Verification
Previously we looked at visual data verification using Python and Pandas. Here we shall extend this to look at geospatial data verification of the earlier Oklahoma Injection Well Dataset. Gesopatial data can be managed and plotted using Geopandas – a geospatial extension to Pandas. This comes with some basic basemap data, but you will probably ...

High Resolution Printed Maps

In the past we were able to offer high resolution printed MapPoint maps via a partnership with Mattys Consulting. Maps could be ‘wall sized’ whilst retaining full resolution; and supplied as printed paper, laminated, or as a PDF. Mattys Consulting are now able to offer these services again for Microsoft MapPoint, Caliper Maptitude, and other ...

Data Quality and Public Trust 1

I recently published a series of Maptitude maps of earthquakes. A couple of these mapped recent Oklahoma earthquakes against saltwater disposal wells. Much of the public commentary has blamed these earthquakes on hydraulic fracturing (aka “fracking”) by the oil industry. However the earthquakes do not correlate with the fracking in either time or space. Instead ...

Mapping Earthquakes

Maptitude can also be used plot earthquakes, examine patterns in earthquakes, and even look for correlations with other factors such as oil industry activity. Earthquake catalogs from recent years can be downloaded from the US Geological Survey at http://earthquake.usgs.gov/earthquakes/search/ . For the following maps, the data is downloaded as a CSV (comma separated value) file, ...
