I've just started a new job in Los Angeles and would like to get my new company (consulting groundwater geologists) up and running with MI. However, I've never worked in the US before and I'm not familiar with the types of data available here. I've used digital 1:50,000 topo maps in Canada which can be obtained as .dxf files and I was wondering if there is anything like that available in the US. I've also seen the USGS scanned images of the 7.5' quad topos. How difficult is it to download and convert these into MI format? Is there some software that can do it or do I have to register each one manually. And what about the DEM's? Ideally I'd like to be able to decide if I should try and do this myself or just go out and buy packaged data. We'd probably need something like 50 - 100 of the 7.5' quad sheets. Any idea what this might cost commercially? I'd also like to get an MI file with the townships and ranges for California. The company also has a CD with a database of water quality data and drinking water source locations put out by the Department of Health, but a large percentage of the wells have no lat-long record and are therefore useless. Is anyone selling a more useable version of this data? The same goes for the oil and gas well records that are currently being digitised by the Department of Conservation. Finally, is anyone aware of any MI add-ons designed for groundwater geology? I've used Discover and can see how it might be useful but it's really meant for mineral exploration. Many thanks in advance. Cheers, ___________________ Tim Warman MSc Geologist & GIS Specialist Manson Warman Assoc.
