Geolytica Inc.

Company Description

Geolytica is a company engaged in development of GIS geocoding software.
Geolytica Inc. offer our own standalone software server package for companies who need data geocoding and analytical services, solutions for commercial clients involving requirement studies, system design, and application development using open tools for GIS systems. We are involved also in mineral exploration and exploitation worldwide.

We also provide a variety of GIS data services for both commercial and non-for-profit applications.
The data services we provide include but are not limited to:
Real Time Geocoding:
We strive to provide the most reliable and accurate geocoding services for Canada and the USA. Using our XML port you can integrate geocoding functionalities into your application in real time. We currently provide forward and reverse geocoding of street addresses, postal / zip codes and street intersections in both the USA and Canada. Both XML ports provide the same quality of geocoding; but the Commercial Port has higher priority process scheduling, hence queries execute faster. Users of the commercial port also receive unthrottled use of the service, and priority response on support queries.
How it is done:
The base data set is provided by various agencies which gather GIS data (one of our Canadian data sources for example is compiled by GeoBase, whereas data for the USA are mainly based on the TIGER line dataset of the US census bureau) . This data is then filtered by our system for inconsistencies. (We find that some of the data we acquire from these sources is incorrect possibly due to human data entry error. We have developed a way for discovering and correcting the majority of such errors. )
After that raw data has been corrected and imported it is algorithmically processed to geocode locations.
Forward Geocoding is done by building a "line" (in most cases) or a "curve" through the data points representing a street then doing an interpolation based on the input street number of the location, or finding the intersection of two streets. You can input a location string in many different ways, as a civic address, intersection, geographical area, etc. Our location parser will take care of identifying all location components and geocode the result against our database of the north america's road network, and geographical features. Our customers use this information to build intelligent location aware applications.
Reverse geocoding is done by first finding the closest street segments to the input point out of a two dimensional matrix containing roughly 3 billion elements. Then we compute the closest point on the segment and return this street address along with the area's postal code and other information such as the county name, metro area, nearest intersection, nearest major intersection, the positioning of the nearest street relative to other streets, etc. . Our customers use this information for fleet management, cell phone tracking, Raw data analysis, Emergency 911 services, GPS tracking and route planning.
Batch Geocoding:
We process batch geocoding jobs for our clients. The rates vary with the size of the batch. Contact us to find out more.
Canadian postal codes geocoded Dataset:
We offer some of our data as a batch download for those wishing to build commercial location based applications. One example of our batch products is our geocoded Canadian postal code database.
We plan and build location based web services at affordable consultancy rates. Some projects we undertake from the basic hardware requirements to the software implementation. Others simply involve proposing ways to improve existing applications. If you have such a project to complete, chances are we have the best solution.
