![]() ![]() Keeping the Trekker's 15 lenses free of debris (and bugs) is a common challenge for the teams capturing immersive panoramas of ever-wilder locations. But one thing you won't ever see in the images? Surprise spiders. In the vicinity of Portsmouth Harbor, NH the resulting image is geo-referenced to about +/- 3m.Ģ) Because of MATLAB's poor rendering performance on the Mac platform, my experience has been that maps plotted as in the example above produce white gaps whose cause and resolution are unknown.Google Street View continues to expand its range, taking desk jockeys to some of the planet's most remote corners. The algorithm was determined by trial and error (as the API provides no way to query for the spacial bounds of an image), and therefore will likely produce poor results for some locations. Imagesc(XX,YY,M) shading flat colormap(Mcolor)ġ) The estimate of the X and Y coordinate vectors are just that, a guess at an algorithm for determining these values from the images size and zoom level. The following code produce the attached screenshot: None-the-less it remains a very handy function for quickly plotting data on a map. Note, the key requirement places limitations on the portability of this function, as the key, and therefore the function is necessarily tied to a domain name and therefore (usually) a physical location. The key may be obtained here: (click "Get a Key") To utilize the Google Maps API up to 25,000 queries per day, one must obtain a Google Maps API Key, freely available from Google. One may utilize the Google Maps API without a key for a limited number of queries per day. ![]() For each marker one may specify the location, size, color and optional label.ĭefault values: Zoom 15, MapType = 'satellite', Height = 640, Width = 640 The desired height and width of the image (in pixels) may be specified as well as the "MapType" (one of roadmap, mobile, satellite, terrain, hybrid, mapmaker-roadmap, mapmaker-hybrid) and up to 50 Google Map markers. In addition, an estimate of the X and Y coordinate vectors are returned in UTM coordinates to facilitate easy plotting of additional information on the map from within MATLAB. ![]() The image is returned as a raster array and a color map. The function get_google_map.m uses the Google Maps API ( ) to retrieve a google map image from Google given coordinates of the center of the image and the desired zoom level (default 15). ![]()
