Irriworks at 2010 GisDay
- In the morning, meeting and poster session at the Sala Magna of the Palazzo Steri
- In the afternoon, workshops on remote sensing and Webmapping at the ARCA Consortium.
Title of the day "GIStales: data, people and tools."
As you know the program IrriPro v.2 uses GIS data from the Google Earth service to perform the survey. In this regard, during the event will be presented a job and a poster made by the company in collaboration with the Faculty of Agriculture, entitled "GIS DATA TO GOOGLE EARTH: RELIABILITY AND USE IN IrriPro". The following is an excerpt of the poster to be presented at the event:
With an innovative and powerful technology you can make "the relevant horizontal and vertical alignment to you" by Google Earth and get a 3D model of land that you can use in your design. Through this console, you can perform a topographic survey of the land simply by identifying the area to be detected. You can use this feature to: | |
- Surf in 2D or 3D, as in Google Earth by entering coordinates or name of the place. - Develop the satellite imagery identified by choosing the precision level of survey from 25 to 2500 points collected from a processing time of up to ten minutes |
IrriPro matter the satellite imagery and GIS data (DEM as ASC file) to calculate coordinates and dimensions of each object that will be included in the workspace of the software. The DEM (Digital Elevation Model) product is a raster data model, in the case of 2500 detected points, it consists of a matrix square mesh of 50 rows and 50 columns. The characteristics listed in the plano-altimetric DEM are georeferenced to the UTM-WGS84. | |
Knowing the plano-altimetric trend of the land, slopes and elevations will be allocated to the elements (such as pipelines and regulators) according to their position. Throughout the work area, the elevations (listed next to the mouse cursor) were obtained through a SPLINES-type interpolation procedure of DEM data. Intercepting points of equal altitude with lines you get the various contour lines. |
