QMap – A field data collection program using QGIS
QMap is a field data collection application built using QGIS and python plugins. It is very similar to QGIS but with an interface that makes it easier for most people to use for data collection in the field and was designed to work with windows based tablet devices. Custom forms are built using Qt Designer and follows a convention based approach in order to save configuration. The application also supports QGIS project files (.qgs) so that you can easily use it with your QGIS desktop mapping projects.

A handy little FREE software package for planning of GPS Missions provided by Trimble is a powerful little GPS uttility that you can run from your laptop or PC allowing you to analyis GPS coverage for any given day helping you to determine visibility for GPS, GLONASS, IGSO and geostationary satellites. When you know what times of day have the best optimal GPS coverage then you can better plan the rest of your survey work.
The planning software allows you to optimize your base destination region with multiple station locations allowing you to determine where it would be best to record observations, determine elevation masks, generate graphs showing satellite coverage, DOP coverage, and create sky plots of GPS satellites.
[Update – Trimble now offers an online version]
Over the past decade Real Time Kinematic (RTK) surveying with Global Navigation Satellite Systems (GNSS) has become common practice in geomatics. RTK surveying can allow people to achieve relative positioning with centimeter (cm) precision, however there are several important factors that need to be considered and thus a need for a good guide of best practices (equipment calibration, errors, multipath, geometry, etc.).
The Province of B.C. launched a new version of iMapBC. This popular public mapping tool can be freely used to visualize and analyze hundreds of geographic government datasets. Content includes location of municipalities, public and private property, land use tenures, heath regions, roads, rivers, and topography.
As a reliable source of up-to-date and authoritative data, iMapBC helps inform a broad range of decision makers from oil and gas companies to First Nations. This means they spend less time doing paperwork both inside and outside government, and more time developing projects that generate jobs for British Columbians. Whether you’re a long-time user or brand new to iMapBC, try it out. Look for it, and other applications on the DataBC Website.
