About Us

Lotinfo was founded in 2005 to address what we consider to be the primary challenges for managers:

Bringing together quality mapping and information from public, commercial, and, most importantly, in-house sources.

Functionality that allows you to work interactively with the data, experiment with “what if” scenarios in a geographic context, analyze trends and identify opportunities.

Ease of use for decision-makers—not just for tech people.

Security. Applications that provide access to public data, but keep private data, updating and analysis within the client’s firewall.

Lotinfo is jointly owned by Space Track Inc, and ITSoft Solutions—two GIS and IT consulting firms whose principals together have 30 years experience as GIS (Geographic Information Systems) and IT consultant to industry, government, and non-profit organizations. In these assignments, the emphasis has been on parcel level mapping and data to support location-based decision making, The two firms have been working together on client applications for over ten years.
