[QUOTE="BrokeInBendigo, post: 608857, member: 18943"] What diggit wrote about scale Also it takes ages to load that much detail! File size, noise an software performance are factors Keep in mind you are looking at *geological lines* and faults. The faults generally run N-S. Those other squiggly lines are, without looking at that dataset, geological unit boundaries. That is to say, where different units and formations meet. They are not faults! For example, you may have alluvium along a watercourse, some colluvium around it where rocks are brought down the surrounding hills, and some other general formation where there are no watercourses or fluvial deposits. The boundaries between these units are the squiggly lines. Geovic is amazing for a web app but it is very confusing. Check out the pre-digital geology map series and learn to read that, then have a look at the digital data in geovic. Or use a GIS software and import the data for an actually usable experience. Edit: a dataset may cover large areas in 250k, and then certain smaller regions within that area are covered by 100k. So for some places you can use 100k only, so long as you are ok with the high detail and performance, but you still need the 250k layer for regions 100k doesnt cover. [/QUOTE]
