The advantages of the services on the web-GIS - wmo.int · Web-GIS технологии GeoMixer...

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

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

1 Decade of June

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.);

• The ability to provide timely information

The advantage of users

1. Digitalize their fields according to the

current or previous years;

2. The possibility of making

observations and marking in online

mode;

3. Swift control of the state of crops and

to the formation of operational reports

to the Ministry of Agriculture;

4. Rapid assessment of productivity in

each field;

5. Analysis of the spatial variation yields

(soil fertility) in the large fields

6. Analysis of long-term productivity of

land
