Interactive online mapping with XML for agriculture information system at district level
Objectives
To generate thematic maps automatically that correctly and effectively present map based visualisations of geo-data sets selected by the user.
To provide all necessary user interactivity while requiring no special software to be installed on the user’s side except IE 5.x or later Web browser.
To provide remote, prompt and effortless access to remote Agriculture Information at district level through the WWW.
Location and Extent
The agriculture information system for Mahaboob Nagar is selected as the location for development of Interactive Online Mapping with XML. The available extent of this district is covering Latitude 150 50’ to 170 15’ N and Longitude 770 15’ to 790 15’ E. This district is having very moderate rainfall and also experiencing the low yield of agriculture.
The periodic observation of chemical constituents of cultivated land and developing Agriculture Chemical map to aide the Agriculture Department for suggesting suitable crop practices and management. The changes in the chemical constituents of farms and nutrient levels which helps in healthy growth of crops, if properly monitored then proper proportions of fertilizers can be decided for effective crop output.
Data Sources
The input required for developing agriculture information system at District level were Topography sheets covering entire District in the scale of 1: 250,000. The Department of Agriculture, Hyderabad AP, has conducted soil-sampling surveys for the entire District of Mahaboob Nagar considering various parameters both physical (soil depth, irrigability, texture and land capability), nutrient availability (nitrogen, potassium, phosphorous, Iron and Zinc) and soil solution.
The data pertaining to the parameters together with geographic features were obtained from Department of Agriculture. The broad classifications of these thematic data are provided to produce a small-scale map. The expected output from this Agriculture Information System would help the decision makers or farmers to cultivate suitable crop type, crop rotation and cropping pattern together with proper composition of fertilizers, pesticides and other chemical compounds to achieve the healthy growth of agricultural products.
Agriculture Information
Agriculture is one of the oldest industries. Late 1600’s inventors began to develop machinery for planting, cultivating and harvesting crops. During 1800’s Scientists began to identify the chemicals that crops need to grow, for ex: legumes are useful for crops rotation, because the plants incorporate atmospheric Nitrogen into the soil. Scientists also identified other elements that crops need such as Phosphorous and Potassium. During 1900’s Scientists have developed better stronger varieties of plants and livestock and highly effective fertilizers and pesticides.

Texture of the soil depends on the size of mineral particles. Sands are the largest particles. The individual grains can be seen and felt. Silts are just large enough to be seen and Clays are microscopic. Pedologists divide soils into textural classes according to the amount of Sand, Silt and Clay. For example: The mineral portions of soils classified as loam contains from 7 to 27% of Clay and less than 52% of Sand, in SiltyClay more than 40% Clay and more than 40% of Silt. Texture helps determine how thoroughly the water drains from a soil. Sands promote drainage better than clays.
