Mapping Options

Summary of what does and does not work:

What works (easily):
Google Earth:
Pros: very easy to use; easy to print map (either directly or via extraction to Word); easy to scale up or down; locator makes finding field area easy; streets, towns, and rivers labeled; possible to put icons and field borders on fields (via "My Places" layer)
Cons: must download program (free); scale not easy to set exactly
NRCS Web Soil Survey:
Pros: web-based and free; locate fields by a large variety of methods including address, state/county, latitude/longitude, TRS; township/range shown (in some areas section borders shown); streets, cities, and rivers labeled; scale precise and adjustable; easy to print image directly, but it is not clean (only a 1/2-page map with webpage clutter on it)
Cons: often unavailable and sometimes a bit slow; (recently) can only copy image on PC using Internet Explorer, not a Mac using Firefox; will not work on Safari at all
Terra Server:
Pros: web-based and free; locate fields by address, latitude/longitude, or point-and-click; easy to use; scale shown; easy to print full-page images and/or extract to Word file
Cons: no labels (no street, city, or stream names); older maps (1994); cannot adjust location of maps to precisely fit needs (i.e. set map borders)
What doesn't work (well):
Google Maps: shows aerial photo but will only print street maps (not terrain/aerial photo) without a screen capture
Oregon Imagery Explorer: must use Safari; cumbersome and difficult to extract image

Quick Direct-Printing of Grower Field Maps off the Internet

Google Earth
Install: if the program is not already installed on your computer, download Google Earth and follow the instructions for a free download
Open: start Google Earth
Locate area: on the "Fly To" tab (upper left corner under "Search"), type in the town nearest to the field (i.e. "Harrisburg, OR")
Prepare screen: Under "View," turn on "Scale Legend," and if you don't want them to show on your printed map, turn off "Navigation bar" and "Status bar"
Locate field: select an area of interest by holding down the left mouse button and dragging map to locate your field(s) near the center of the screen. Try to include at least one labeled road on the map. You can also use the arrow keys to move the map around in a linear manner, or you can zoom in and out with the scrolling wheel on your mouse.
Adjust scale: to print a nearly 660-scale map, adjust the map so the scale bar (at the lower left corner) is as close to 2239 feet as possible. It is usually not possible to get it exactly at 2239 feet. The easiest way to accurately adjust scale is to use the "+" and "-" keys on your keyboard.
Print: print directly from Google Earth by selecting the print icon on the toolbar (upper part of the screen), selecting "Graphic of 3D view" and proceed to print. This generally results in a fairly clean (uncluttered) 1/2-page map. To print full-page maps, you can copy the map and paste onto a Word document (see Preparation of Full-Page Vertical Grower Maps from Google Earth below).
NRCS Web Soil Survey
Open: in Internet Explorer or Firefox only. You can't "copy image" in Firefox (a recent development: older versions of the site allowed you to do this). You can do a direct print in Firefox, however. The site will not work at all with Safari.
Start program: click "Start WSS"
Locate field area: under "Quick Navigation" either on the left side or bottom of the screen, select the way you want to locate your field. Choices include address, state/county, latitude/longitude, and TRS, or simply select an area by holding down the left mouse button and marking a box over the area your field is in and releasing the mouse button (will take several repeats to get to your field area).
Locate field: when you are in the approximate area of your field, you can drag the screen map to your field by selecting the little hand on the tool bar (top of screen) and holding the left mouse button down while you move the cursor across the screen in the direction you want the map to move (i.e., to move the map west, hold the left mouse button down and move the map to the right).
Adjust scale: to print a nearly 660-scale map, click on "scale" and adjust the bar as noted, then selected 1:3960.
Print: "File" then "Print" (depending on your browser). This is not a clean full-page map: it is only a 1/2-page map that has webpage clutter on it. To print a good, full-page, clean map, see "Preparation of Full Page Vertical Grower Maps on the Web Soil Survey Website."
Terra Server:
Open: website (works well in Internet Explorer, Firefox, and Safari)
Locate field area: select a field by address or latitude/longitude, or simply select an area on the green map (with a click) and continue to click until your field comes into view (will take several steps, and you most likely will need to move the map up-down-left-right). Due to the lack of street and town labels, this can get a bit confusing if you are not already familiar with the area.
Adjust scale: to print a nearly 660-scale map, use the second most enlarged map setting
Print: select "Print" in the upper right of the blue box and print the map
