gis application development basic problems i faced and soln

   Frihost Forum Index -> Computers -> Software

i was given a proj. on devlopment of gis application which based on some data can predict the flooding areas of india. to make it more simpler i have to concentrate only on rain and river data. they provide me rain data but i was not having river data. so the problem begins how to enter above 300 entries into database.

a simple solution was to get the data into text file and then by file handling of any programming language the data can be inserted into database.

i used this link to get the lattitude & longitude of the river ganga http://graargh.returnstrue.com/rajdeep/maps/tools/latlong_tool/v7/lat-long-tool_v7.html


then used this code to handel the file:

Flood Information System
• Flood Information System contains no data. It’s a Flood Model System which determine the rise in water level of river Ganga due to the rainfall in near by areas
• This is a simple model which first determines the catchment area.
• Then it calculates the water runoff in that catchment area due to previous two days rain.
• Runoff1 of previous day=k1*avg(CA)
• K1 is a constant it is taken 0.6 here which implies 60% of previous day rainwater is contributing to water runoff.
• CA is the catchment area
• Avg() is a function which returns the average rainfall of that catchment area supplied to it as an argument.
• Similarly, runoff2 for day before previous day is calculated where k1 is modified to k2 whose value is 0.4
• So, rise in river water level due to rainfall is given by:-
• deltaH=runoff1+runoff2

a simple solution was to get the data into text file and then by file handling of any programming language the data can be inserted into database.

i used this link to get the lattitude & longitude of the river ganga http://graargh.returnstrue.com/rajdeep/maps/tools/latlong_tool/v7/lat-long-tool_v7.html

i was given a proj. on devlopment of gis application which based on some data can predict the flooding areas of india. to make it more simpler i have to concentrate only on rain and river data. they provide me rain data but i was not having river data. so the problem begins how to enter above 300 entries into database.

a simple solution was to get the data into text file and then by file handling of any programming language the data can be inserted into database.

i used this link to get the lattitude & longitude of the river ganga http://graargh.returnstrue.com/rajdeep/maps/tools/latlong_tool/v7/lat-long-tool_v7.html


then used this code to handel the file:
