watch market mapping 2 disaster response Uses New Tech M apping companies are providing the data needed by both those in the midst of a disaster and those who need to learn its impact Esri interactive map Using live data from USGS and Waze an Esri interactive map visualized active wildfire locations and traffic alerts for Northern California during the recent wildfires Through Waze the map incorporated a new technique to group traffic alerts at locations with a high density of alerts This method enabled faster and more effective visual analysis in areas where many alerts would normally overlap Active fire data displayed locations of large fire incidents using data provided by the U S Department of Agriculture Forest Service and the Geospatial Multi Agency Coordination group GeoMAC and provided near realtime understanding of the situation on the ground Fire Perimeters Mapbox published a U S map providing updated information on fire perimeters in relation to specific DigitalGlobe natural color satellite image of wildfires note smoke Date October 10 2017 locations and addresses using the best available data from GeoMAC and agencies and first responders on the ground Coupled with up to date satellite imagery from DigitalGlobe the tool helped those affected by fires get information about their family friends homes and businesses DigitalGlobe Imagery DigitalGlobe collected on Oct 10 high resolution satellite images of the wildfires using the Shortwave Infrared SWIR sensor on its WorldView 3 satellite The satellite Targeted Base Station Simplifies UAV Mapping 32 GPS World www gpsworld com november 2017 Santa Rosa DigitalGlobe color infrared satellite images of wildfires note smoke Date October 11 2017 is able to pierce through wildfire smoke to see where fires are burning For comparison the ground and the fire line are completely obstructed by smoke in the natural color image of the same area see the larger overview image in above screenshot On Oct 11 DigitalGlobes GeoEye 1 satellite took both natural color and Very Near Infrared VNIR in the above image burned areas appear gray and black and healthy vegetation is red T he Trimble GNSS Smart Target Base Station provides high accuracy mapping from unmanned aerial vehicles UAVs It has a survey grade multi frequency multi constellation GNSS reference station with a foam Ground Control Target and carrying case The Smart Target Base Station logs the raw GNSS observables required to perform centimeter level post processed Differential GNSS positioning of UAVs and acts as a photo identifiable ground control point GCP for quality control The target base station is supported by both the Applanix POSPac UAV GNSSinertial post processing s o f t w a r e f o r d i r e c t georeferencing on UAVs and Trimble UASMaster photogrammetric software Users can place the foam target with its receiver in the project area and stake it down With the included smartphone app or web user interface users can remotely begin logging the raw GNSS observables data collected by the target At the end of the mission the user retrieves the target and downloads the raw GNSS data along with the data collected from the Trimble APX UAV GNSS inertial system installed in the UAV Global coordinates of the reference station are computed automatically using the Trimble Centerpoint RTX post processing service in POSPac UAV or if local coordinates are desired the foam target can be centered over an existing reference point
