For those planning some caching activities in rural parts of agro-Manitoba there are a couple of sites that may be of interest, especially if you have high speed internet.


Manitoba Agriculture
http://geoapp2.gov.mb.ca/website/mafri/index3.html


Manitoba Riparian Health Council webmapping tool
http://www.riparianhealth.ca/tools_mapviewer.html


See detailed orthophotos, property lines, crown land parcels, hydrology and all sorts of interesting layers of information. You can also measure distances and get coordinates. If anyone knows of any others, let us know.


Enjoy,


Dragonfreys

Here's an example.



Note the coordinates in UTM Nad83 along the bottom left as you move the cursor around. You can turn layers on and off depending on what you need. The ruler lets you measure as the crow flys distances and area.


Could be useful?

Here's another online mapping application that Magellan users probably know about, but I just discovered.


http://www.magellangps.com/en/products/webviewer/default_j.asp?map_name=_ca_topo&load=yes


It lets you look at their topo Canada product where ever you like and even download selected portions of it for a price. Now you can decide for yourself if it meets your needs.


The more I learn about Magellan the more I am impressed.

Not to forget google maps and google earth.

I'm not sure how many geocachers out there are GIS (Geographic Information Systems) users (Junglehair is the only one I know so far) but GIS systems are designed to store, manage and query geographic information so they are ideal for planning cache hides and finds. If you are interested here's some information relevant to Manitoba that makes it easier to get into.


First, Manitoba is the only province I know of who has released the bulk of their GIS data for free to the public via a website program called the Manitoba Land Initiative (http://web2.gov.mb.ca/mli/). You can get 2 m resolution orthophotos for all of southern Manitoba, topographic features at 1:20 K, cadastral (property lot) layers, land use/land cover, digital elevation models and more GIS data than you can shake a stick at.


Second, Manitoba Schools a couple of years ago decided to buy group licences for the most popular and expensive GIS software packages available from a company called ESRI. So any school in Manitoba with computers that can handle it, can install the software at no cost to the schools. GIS is also being integrated into the curiculum, even in Elementry Schools. So for social studies, instead of colouring and labeling a map of Canada by hand, kids are classifying the provinces and auto labelling from the data.


Third, there is a huge online community building open GIS software. I have to use commercial stuff for work so I haven't checked out much of this yet, but there are some amazing developments being made with open source GIS. If anyone has some insight into some of these I would be interested to hear about them.
