How accurate are the images in Google Earth?

The theme of orthorectified  and satellite images’ precision of Google Earth is a record question in search engines; in these days where confusing precision with tolerance is as easy as losing the GPS in the taxi, it would be good to make a couple of analysis about whether or not to use these data for […]

View coordinates in Google Maps, using ANY! other coordinate system

Until now it has been common to input UTM and geographic coordinates on Google Maps. But usually that supports keeping the datum is WGS84 Google.

Indeed, you get better resolution, but no more coverage than what we see, what these tools offer is output better quality, for example to view, print, save, or send to […]

StitchMaps, common problems

Stitchmaps was one of the best applications that were made to create orthophotos from Google Earth captured mosaics; I spoke about how it works long ago.

Google Earth; visual support for cartographers

Google Earth beyond being a tool for general entertainment has also become a visual support for mapping, both to show results as to review if work done is consistent; it also serves as a teaching tool for geography or geodesy classes.

Draw on line on Google Maps

Let’s imagine that we need to send a client a sketch map so he can view it online or in his GPS Navigator. For example, if we have a parcel for sale with the path to get there and its road’s indications. Another example could be an area of the MODIS satellite view from that […]
