THE SURVEY BY GOOGLE MAPS/EARTH

Thanks also to the revolutionary technology for survey from the Google Maps/Earth on-line service, available within the program, you can perform the topographic survey of the area where you implement the system without moving from your PC: You will get 3D model of the land: this feature is used to perform the topographic plano-altimetric survey of the area where will be designed and built the irrigation system.

Through this console you can make a topographical survey of land simply by identifying the area to be detected . The user can use this feature to:
  • Surf in 2D or 3D, as in Google Maps 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.

RELIABILITY OF THE GIS DATA IN GOOGLE MAPS/EARTH

From studies carried out by the company Irriworks, it appears that the quality of data extracted from GIS service Google Maps is comparable to the same level of a technical mapping on a scale of 1:10,000 and then sufficiently reliable for the design of irrigation systems. In addition, you should not underestimate the great difference of time, resources and equipment to be used for the construction of a detailed survey: For the areas under study, this has required a time of 3 months compared to the few minutes used to extract data through the GE service, whereby it is possible in real time and in the areas where you do not have a traditional cartographic support, to obtain a reliable representation of the difference plot.

The solution for any need

IrriPro softwareIrriPro is available with FREEWARE license for small systems and with basic features, with fully featured for limited time or with never ending LIFETIME licenses.

USER-FRIENDLY INTERFACE

IrriPro has a CAD-style user friendly interface, designed to be used by engineers, agronomists and other technicians. They have all the analisys tool needed to estimate the consequences of any design choice and to represent the trend of any physical parameter.

WIDE DATABASE

The DB is not a list of passive elements, but a way to make the most of the software using existing material on the market.

QUALITY OF THE PROJECT

The irrigation software IrriPro is the only tool that optimizes the use of water and improves the distribution uniformity, increasing the system efficiency and ensuring the correct distribution of water and fertilizers. Moreover IrriPro reduces the system realization costs, improving quantity and quality of agricultural production.
