Dear GIS wizards
Our small volunteer group researches whale behaviour. We cruise along with a
group of whales, recording every now and then, on a Pocket PC, the position
of the whales (lat/long), position of influencing factors like commercial
whalewatch boat, and environmental conditions like water depth, temperature
and weather, and whale behaviour. All this is put into a data file (in an
XML format actually, but that's neither here nor there).
What would be nice would be if I wrote a data conversion program to convert
this data to some standard- format GIS file. Then the new file could be fed
into a GIS program to draw maps of coastline or seabed, with superimposed
whale and boat tracks, maybe showing points of interest like where
whale/vessel interactions occurred.
We can't afford to buy a proper commercial GIS program unfortunately, but a
shareware GIS program would be within our budget.
I need some advice on what would be a good choice of GIS data format.
Obviously to be able to write the data conversion program, I will need to be
able to find out the exact details of the internal format of the GIS data
file -- a specification of the format would be fairly essential. It also
would be good if the chosen GIS format is not the most devilishly
complicated one, so the programming task will be simpler. Finally, of
course, it needs to be a GIS format that a good GIS shareware program will
support.
So -- would appreciate any advice on a good choice of GIS file format,
where to find information on what the exact internal file format is, and
advice on good shareware GIS programs. I have Googled an awful lot but did
not have much joy. Thanks so much.
-- Bill (Sydney Australia)
