Availability - Get access to the system can be in any place and at any time, it is enough to have at his workplace Internet access. Easy - Work in an ordinary browser. The system does not require maintenance by the administrator or the GIS specialist. Teamwork - To share your project with colleagues or with the whole world - just send a link or embed the project in your own website using the API. Access control - You can create both public and private projects, giving them access only to selected users - to view or edit.
The advantages of the services on the web-GIS:
● Data Merge external Geoportal and local custom server
● Mosaic covering satellite images
● Raster layers (satellite images, Aerial photographs, raster maps in the format? GeoTiff, ERDAS Imagine, JPEG, PNG, etc.)
● Vector layers (points, lines,? Polygonal objects in formats? ESRI ShapeFile, MapInfo MIF / TAB, GPS-tracks in GPX format, Text and tabular data, From Excel and MS SQL 2008)
● Address search
● Drawing objects, Alignment markers
● View and download data
● Access rights to the geo-data
Potential of Geoportal
Web-GIS технологии
Рисунки: В. В. Гохман «DATA+»
Web-GIS-technology – technology to create web mapping
services, geographic information portals (geoportals) to the
Internet or corporate GIS with access to geodata large
companies, with a regular Internet browser.
Web-GIS - (web based Information
service) - web-oriented information
services or systems.
Web-GIS технологии
GeoMixer WEB-GIS - a custom web interface
for geodata and geo-service, having the tools to
create and edit projects.
Solution
ESRI GIS Portal Toolkit
(USA) -
This product is open source, which allows the
detection and use of geospatial resources,
including data sets, raster, and Web services.
Geoportal Server supports standards-based
center and metadata discovery applications.

Vegetation Index - Direct estimation vegetation state
Vegetation condition is determined based on measurements in different spectral bands based on absorption and reflection characteristics of plants, The main index is NDVI:
• Greenness indices; • Indexes of efficiency of use of light; • Soil indexes; • Indices moisture content; • And etc.

Early warning of drought, Akmola region

2 Decade of May
Compare the current values of the index
NDVI multi-year highs, lows and
averages allows for early detection of
the onset of drought in a given territory
According Vitkovskaya I., Kauazov A.,
Batyrbayeva M. at all.
The shift of the season - late sowing
The difference in the amount of above-ground biomass of the current season and another
-18%

Satellite service (basic functionalities)
• Analysis of vegetation in a particular state of the field at any moment growing season;
• Comparison of crop conditions and their status in the previous seasons, and other fields;
• Determine the type of cultivated crop field in the current season and in previous seasons;
• Assessment of impacts of negative factors (frost, drought, insect infestations, etc.);
