lesson eight a us docos created after June 2017 in this lesson we will
demonstrate how to open and manipulate data layers using Adobe Reader DC and
Adobe Acrobat Pro we will also learn how to use basic tools like panning zooming
and making measurements lesson for a or B for C and for D of the National map
training provide instructions for using the national map download client to
download data and maps including u.s. topo maps this lesson will focus on
using u.s. topo maps in the new geospatial PDF format using acrobat
reader DC and adobe acrobat pro the instructions apply to both the u.s. topo
maps and geospatial PDF format were produced by the usgs beginning in June
2017 the geospatial PDFs are ISO 32000 compliant the terrico toolbar used with
older u.s. topos does not work with these products however this video will
demonstrate several alternative tools native to Adobe find the file you
downloaded and double click on the file name the file will open in either Reader
Pro depending on what you have installed click the enable all features if
necessary expand the map by clicking on the arrow to collapse the right hand
pane click on the layers icon to open the layers expand the layers by clicking
on the plus signs you can turn layers on and off by clicking on the I to the left
of the layer names there are several options to zoom and pan the map click on
the plus and minus icons in the Adobe toolbar above the map to zoom in and out
if you've used Adobe Reader or Adobe Acrobat Pro before and have already
turned on the Adobe zoom select tools the plus and minus icons will not be
visible to reset the toolbar go to view show hide
Toolbar items show select and zoom tools and click on reset selected zoo
you can also enter or choose a percent of actual size in the window to the
right of the plus icon in the Adobe toolbar
to turn on other Adobe tools go to view show hide toolbar items show select and
zoom tools select the tool you want such as the marquee zoom or the loupe tool or
turn them all on by clicking show select and zoom tools the marquee tool allows
you to zoom in to an area of interest by drawing a rectangle over the area hold
down the left mouse button and drag the cursor over the map
select the continuous zoom tool to zoom in and out click on an area on the map
while holding down the left mouse button and move the cursor up and down you can
also use the scroll wheel on the mouse use the loupe tool to see an area in
more detail click on the loop icon and click the map use the slide bar or the
plus and minus buttons to zoom in and out you can also zoom by holding down
the control key and using the plus or minus icons on the keyboard
the page resize tools display the map at its actual size fit the map to the
screen or fit the width of the map on the screen use the hand tool to pan
around the map
the up-down left-right arrow keys may also be used to pan you may not pan if
the map display shows the entire map page the pan and zoom window tool allows
you to change the magnification and drag the box to pan across the image
right-clicking on the map is another way to select some tools
to display the coordinates on the map click on tools and then measure tools
click on the geospatial location tool a window appears at the lower right of the
map display showing latitude and longitude inside decimal degrees
coordinate readouts for us topo geospatial PDF maps are always latitude
and longitude on nad83 wgs84 to measure distances and areas click on the
measuring tool two windows appear on the map display one with options for
snagging types and measurement types one for results there are three types of
measurements distance between two points
perimeters
double click to stop drawing and areas
single click to close polygons and stop drawing click on the selection tool and
hover over the drawn line perimeter and polygons to see the results of your
measurements all right mouse-click allows you to
delete the graphic the measuring tools also function as a simple type of markup
lines drawn with the measuring tools can be burned into the PDF use file save as
to save a version of the u.s. topo map that includes the user drawn lines these
lines are not part of the u.s. topo layer and once saved cannot be turned
off but can be selected and deleted to change the map display units click on
edit
then preferences
click on measuring geo to see the options
the relatively limited number of geospatial functions is not a
characteristic of the u.s. topo product but rather of the software currently
available to view this new version of geospatial PDF USGS expects more
software for viewing and manipulating these data will become available over
time each u.s. topo file has an attached file of metadata that describes data
sources and production processes this file complies with the federal
Geographic data committees content standard for digital geospatial data the
physical format is XML to access the metadata file click on the paperclip
icon then select the file from the list that appears you can also download the
metadata when you download the geospatial PDF
in this lesson we discussed how to open and manipulate data layers in Adobe
Reader DC and Adobe Acrobat Pro we also learn how to use basic tools like
panning zooming and making measurements in a subsequent lesson options for
printing us topos will be discussed
