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 serious work. Now there´s in ...

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. But: What if we want to see in Google Maps, a coordinate of Colombia in MAGNA-SIRGAS, WGS72 or PSAD69? What if we want to see a coordinate of Spain in ETRF89, Madrid 1870 or even ...

Apparently there is some confusion about what Google Earth paid versions offer; there are those who believe that they are obtained coverage of better resolution. 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 pdf formats, though the coverage ...

In response to some questions I receive, I take advantage to leave the outcome for public use. Some time ago I had spoken how you can insert images linked to Google Earth point, but using Web addresses. In this case I want to show it using a local path: Assuming that the file is set to C: / Users / ...

So far I had read in Yahoo Answers, that it was only possible with the NASA satellites, and that to achieve this was possible only with its own satellite. I am referring to have Google Earth opened and be able to see the Earth as it is, fly and see below the small houses as it is happening at the ...

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. In this case I’m going to get assisted by Manifold GIS to build the quadrants and by Google Earth ...

This is an application that goes beyond the simple, but in practice resolves what we all want to be as simple like: On this side Google Maps —-> Satellite layer Hybrid layer Map layer Topographic layer On this side my GIS program ArcGIS Mapinfo GeoMedia Microstation Bentley Map For a moment I thought it was something similar to what Plex.Earth ...

TRANSLATION NOTES: Please read some comments at the end of this post. A few days ago a friend asked me how to do to see the contour lines in Google Earth using an application called ContouringGE 1.1 that is supposed to work with any 4x version, Windows XP or Vista. And because definitely I couldn’t, finally I did it but ...

Being an “Internet of people” companies have become the first look at the people interconnected with each other, which has given it a value beyond the conventional network. One of the best features is the ...

TRANSLATION NOTES: Please read some comments at the end of this post. Last time we talk about some criteria of why MapServer and its basic installation. Now let’s look at some of its performance in a mapping exercise from the Chiapas buddies (*). Where it is mounted Once installed Apache, the default publishing directory for MapServer is the OSGeo4W folder ...

Taking advantage of a recent conversation with a Cadastre institution that sought with what to publish their maps, I summarize here the most important to return the item bailouts to the community. Maybe in time it’ll serve someone who wants to make a decision or ask for egeomate’s ...

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 day that we hope to ...

One day ago I spoke of the new features that would bring PlexEarth Tools for AutoCAD’s version 2.0, one of the most practical developments that I have seen on Google Earth from a member of the Autodesk Developer Network (AND). Today it has been released the Beta version, which can be downloaded, tested and what is important in these stages: ...

In the previous post we had georeferenced an image that contains contours; now we want to turn it to Civil 3D contours. Converting image curves to digital mode For this there are programs that virtually automate the process like AutoDesk Raster Design, equivalent to Bentleys Descartes or ESRI’s Arcscan. In this case I’ll do it manually, drawing polylines. Smartlines should ...

Earlier we saw how to create contours based on a points’ network taken in the field. Now we’ll see how to do it, from existing curves in a scanned map. As we did with the design of roads, let’s split the process into steps, so that the post won’t go longer than a snake fart. Inserting the image For this, ...

A few days ago I started a development on .NET, with which I hope to settle the Bentley Map’s limitation with its Geospatial Administrator. For this, I caught an old pupil with which we began to egeomate with xfm when he came out from the Comal(*); tasting a ...

TRANSLATION NOTES: Please read some comments at the end of this post. Last year, in November, I made an assessment of PlexEarth Tools for AutoCAD version 1, which among its innovations includes the AutoCAD’s interaction with Google Earth. On this topic there are developments such as StitchMaps, KmLer, CounturingGE, kml2kml; in Plex’s case, in my opinion, one of the best ...

Of the best links I’ve received as Gabriel’s feedback from Argentina who told us about it, a couple of days ago. GPS Babel is a free application tool under GPL license, which runs on Windows, Linux and Mac. Ideal for downloading data from a computer and upload it directly to another. For example, you can be downloading from a Garmin ...
