How to make a map that doesnt look like you did
it in ArcView 2.1

2So you wanna make a map, eh?
- Making maps is an integral and fun part of doing
GIS.
3- Creating aesthetically pleasing maps that also
convey the correct message is one of the - supreme challenges.
4The goal of this presentation is to share a few
tricks and tips that may help you make a better
map.

Useful for organizing information. Make them very
different. Its also a good way to add some
visual pop.

Being consistent with the elements youve chosen
creates a visual unity and harmony to the map

Random or unstructured placement on the page
breaks down the effectiveness. Be mindful of how
elements are arranged with regard to individual
pieces and the page as a whole.

Elements that are related to each other should be
placed near each other.

Consider the final format the map will be in the
beginning. A map or graphic will have different
properties depending on whether its for the wall
or going into a PowerPoint presentation.
13Wow! Neato!, I knowit gets better though..
14Hillshading
- From ESRI
- Shadows drawn on a map to simulate the effect of
the sun's rays over the varied terrain of the
land. - The hypothetical illumination of a surface
according to a specified azimuth and altitude for
the sun. Hillshading creates a three-dimensional
effect that provides a sense of visual relief for
cartography, and a relative measure of incident
light for analysis.
15Swiss Hillshading
Emphasizes the major geographic features,
minimizes the minor features, smoothes irregularit
ies on the slopes, but maintains the rugged
characteristics of ridge tops and
canyon bottomsYou can then simulate an aerial
perspective that makes the higher elevations
lighter and the lower elevations darker.

bit.

By varying background colors, the DEM color ramp,
and a hillshade, cool effects can be created. In
this case a colorful, yet subtle representation
of the topography. Its like magic, only easier

ltBOLgtIntrinsic potentiallt/BOLgt for each stream
reach was calculated for chinook salmon from
attributes of ltITAgtmean annual stream flow
ltbolgt(If)lt/bolgt, valley constraint
ltbolgt(Ic)lt/bolgt, and channel gradient
ltbolgt(Ig)lt/bolgtlt/ITAgt. These attributes were
produced in conjunction with the digital stream
network from 10-m digital elevation models
(DEMs). The stream network was output in an
ArcView shape file format and then imported into
ArcInfo (ESRI version 9.1) for all subsequent
processing. Stream attribute values were
converted to index curves. Consistent with the
most widely applied approach for modeling habitat
suitability (United States Fish and Wildlife
Service 1981 Morrison et al. 1998), intrinsic
potential for each stream reach is expressed as
the geometric mean of values from the
species-specific index curves.
