For the friends who venture out to feel the colorful dust of the road, especially on a bike, I present here a little bit about what the digital processing of spatial data (Gis) can help in lifting the ground to be traversed.
As you all already have noticed, in recent years has grown enormously the availability of resources that can be used for planning a trip in order to know better the stops and routes.Example of this is that the GPS has aided us, updated maps and the famous Goggle Earth,Google Maps, among others.
Whereas the relevant data (altimetry) are important in planning cycle trips, presents a fairly simple technique for digital terrain modeling to be traversed.
There is a Software called Global Mapper that has the ability to recognize different types of images and data. This program has entered data SRTM (Shuttle Radar Topographic Mission) that are characterized by sampling points with information about altimetry. A sensor attached to the space shuttle Endeavour was designed to collect three-dimensional measurements of the Earth’s surface by interferometry (technique of overlap of two or more waves), (VALERIAN, 2004).
Therefore, with a resolution of 90 metres in the horizontal plane, there is a given of altimetry and these images can be purchased..
The big difference is that on this data may overlap altimetry images showing the characteristics of using the surface that most interests us, i.e. the roads.
Landsat satellites CBERs images or can be purchased on the website of the INPE or images from Google Earth itself can be coupled with SRTM data.
Thereby reconcile if information on the surface (land use) with changes in altitude.
Figure 3. SRTM data plus map IBGE with MME transparency about the JPG image of the map and a random script (yellow line) displayed in the form of topographic profile, where you can identify the altimetry of the route more mileage
Figure 4. SRTM data (terrain Modeling) with the overlay map of the IBGE.
In the case of the example shown here use SRTM data and beyond an image of Google Earth, which are actually satellite imagery available for free by Google, a map of the IBGE (Brazilian Institute of geography and statistics) on a scale of 1:50000 called MME, which exists for all municipalities in Brazil, where there is a lot of information of roads paved and unpaved, and can be downloaded.
In the case of this last map (MME), the same is available on the website of IBGE in “pdf”, therefore it was necessary to transform it into JPG and then insert it on the Global Mapper software.
So, if a database with the following information: plans
-SRTM Data (altimetry);
-Map MME (IBGE);
-Google Earth Image.
The great possibility of the use of these resources, in addition to having access to altimetry is the treatment of geographic data, that is, the plans and information loaded on screens are georeferenced in a plan x and y we know as latitude and longitude, so additional information can be calibrated in the database with GPS, that is, if you want to put on screen a way you’ve made and registered with GPS, is possible.
Georeferencing allows calculating distances to set roadmaps and altimetry information, offers the view of the script in the form of Topographic Profile, very important information for the cycle trips.
I hope I have contributed and widespread the technique for application in planning of new exploits in the bicycle.
That’s it, go forward.
