First: please confirm that you have JavaScript enabled, and popup blocking turned off
in your web browser. Here are the
instructions. The Data Download page will not work unless you get this right!
Before you use the Data Download page, you should already have
at least a rough idea of what layers you want to download. If you don't, check out the
"Data Catalog" page
to browse through our holdings and look over the layer descriptions to see if
one or more of them meet your needs. Jot down the layer name(s) and thematic class(es) on a piece of scratch
paper before you move on to the Data Search page.
The Data Search page is designed for quick and efficient
searches - if this is your first time using the Deli, or you are an occasional
user, it can be hard to know where to start. Relax, we'll take you through the process right now.
Step 1. Select your "Search Option"
This is where you choose what kind of search area you intend to use.
- Select "by county" if your area of interest is a single county.
- Select "by area/point" if you want to search for data whose extent is larger or smaller than a single county
Step 2. Select your "Thematic Class"
Thematic classes are a way of trimming down the "Available Layer List" to a more manageable size.
If you want to search for multiple layers that belong to more than one thematic class, you will need to stick with the
default "All Classes" selection.
Otherwise, choose your thematic class from the list
Step 3. Select the data layers you wish to search for
Use the "Avaliable Layers" list to choose the data layers that you would like to search for.
If you would like to search for more than one layer at a time, hold down the Ctrl key as you make your selections.
Step 4. Display your area of interest on the map
Using the map navigation tools, Find your area of interest on the map. Here is a rundown of what each tool does:
Zoom in: Select the tool and then click on the map. The map will re-draw at a larger scale,
centered on the point where you clicked. For more precision, draw a rectangle on the map (click-drag-release) and
the map will re-draw with the area of your rectangle shown.
Zoom out: Select the tool and then click on the map. The map will re-draw at a smaller scale,
centered on the point where you clicked. There is no option to draw a rectangle with this tool.
Recenter map: Select the tool and then click on the map. The map will re-draw, centered on
the point where you clicked. The map scale does not change.
View whole state: Select this tool and the map will automatically revert back to showing the entire state.
Reference Map: If you get "lost" the Reference Map gives you an overview of
the area which you are currently viewing. Depending on the scale to which you
are zoomed, your viewing area will be shown as a rectangle or a star.
Step 5. Search for the data
This is the Data Search tool. With your area of interest now in the map
window, you are ready to search for data. Click on this tool.
- If you chose "by county" as your search option back in Step 1, just click anywhere in the county of interest.
- If you chose "by area/point" as your search option, and you want to search by area, draw a rectangle on the map
(click-drag-release).
- If you chose "by area/point" as your search option, and you want to search by point, just click on your point of
interest.
That's it! You will be rewarded with a "Results" page listing the data that were found
which overlapped your county, search area, or search point.
Step 6. Confirm the results and request a bundle
On the results page, you will see the datasets which matched your search. There are links to the
metadata along with an option to preview the layer.
Once you are satisfied, use the check box(es) to select the
tile(s) for each layer that you want to download. Then enter your email address into the space provided and press
the "get data" button. After you accept the "Data License Agreement", your request will be processed.
If your request is less than 20mb, a popup window will provide you with a web link to the download file.
If your request was larger than 20mb, it will be processed when our servers have time. In that case,
you will be receive an email with instructions on how to retrieve the data (a web link to the download file)
when your bundle is ready.
The data bundle will come with instructions on how to unpack and use the data.
Have fun, and thanks for visiting the Deli – The Minnesota DNR GIS Team
