� Historic data can also be retained and presented.
� Viewable at all scales.
� Flexible:� Single data set can be used
to create multiple outputs.
� Output can be adjusted to the needs of the audience.
� Collaborative process of gathering information about the community and linking that information by location.� The local community manages
the information, � Manastash Mapping manages
the geographic data, links the the geographic data, links the community information, and creates maps.
� The information is used to help people learn about and understand the community. � Tourism� Business development� Education� Historic preservation� More …
Geographic Data
Provides
Attribute Data
Provides Provides the
“Where?”
Provides the “Who, what, why, and when?”
� Types:� Points – Defined by coordinate
� Line – Defined by coordinates of the vertices/end points.
Polygon – Defined by vertices � Polygon – Defined by vertices but closed shape.
� Best for discrete data:� Locations,� Roads,� Boundaries
� Grid� Defined by start point, width and grid size
� Common sizes:� 1m or better for photos
� 10 or 30m for elevation
Each pixel is assigned a value� Each pixel is assigned a value
� Best for continuous data:� Elevation,
� Temperature,
� Land cover, etc.
� Photos are a form of raster data.

� Information that links to a geographic item (point, line, polygon or pixel).
� Can be stored:� In a table in the geographic data layer,� In an external table that is linked to the geographic layer through a
common field – for example,� Name,� Name,� Parcel number,� Unique ID
� Can be numeric, date, or text� Can be calculated in the GIS software
� Geographic values (area, length, etc.)� Values assigned to points based on location (e.g. within a
boundary)� Calculated from other attribute data.
GIS for Kittitas County and Communities Throughout Washington State
Manastash Mapping
A collaborative process
� Community maintains information about places of interest through a database:� Businesses� Recreation� Historic
� Each record can be categorized in many different ways. For example, each business record can be categorized by:
Type (food and drink, services, recreation, retail, etc.)each business record can be categorized by:� Type (food and drink, services, recreation, retail, etc.)� Subtype (café, fine dining, fast food for a restaurant),� Additional information (kid friendly, handicapped accessible, open
Sundays, wine tasking, live music, etc.)
� The community data is joined to GIS data to create maps.� Maps can be created in multiple formats – jpg, pdf, web enabled.� Maps can be created to serve different needs – map for families visiting
the community, places to take a date on a Saturday night, maps for special events, etc.
� When updated community data is joined with the GIS data, the map documents reflect the changes.
� A database is populated with information about:� Businesses� Buildings� Other places
� Work can be done byEDA or Chamber
Work can be done by� EDA or Chamber� Student volunteers� Interns� Community members
� Can include� Contemporary data� Historic information
� Data layers of location (point and/or polygon) are created by the Manastash Mapping.� Points for businesses� Polygons for businesses or
buildings� Tax parcel
Building footprint
Create Geographic data set with linking field
Link geographic and attribute data Tax parcel
� Building footprint� Ground floor buildings
� Geographic layers and database contain a common field used to link the attribute data to the geographic point:� Address� Parcel number� Building name
attribute data through GIS.
Create maps –selecting and symbolizing based on attribute data.
County tax parcel data layer used as the first building
block – gives block – gives building location.
The tax parcel number used as the linking field in the
initial building database.
Points created using editing tools. Field
added to link to business
Business footprint developed by
splitting tax parcel to have polygon for each first floor business
database. Link name address +
zip code (to ensure unique
value).

Uses the tax parcel to link to building data
and the same link name as the points data layer to link to the business table.

� USDA orthophotos available free
� Many counties have purchased high-quality photos.
� Historic� Old photos can be
georectified so they can be used with GIS
� Historic maps
Manastash Mapping use Google Earth base maps (photo, streets, and topography).
� Public base maps are easy to use and cover large areas but you do not have control over the look and they may contain errors.
� Select what data to include,� Decide how to symbolize
data,� Decide what features to label
and format the labels,� Select the background and
supporting data (streets,
� Update the data layers (table or geographic shapefiles) and the map document will reflect the changes.
� In addition to creating maps, you can output the data so it can be used through dynamic
supporting data (streets, rivers, parks, etc).
� Format the map layout.� Output map data (pdf, jpg,
shape files and formatting layers).
� Save the map document – a file in ArcGIS that defines how the map will be drawn.
can be used through dynamic web viewers.� Google maps format� Put on a Manastash
Mapping/Mapbiquity map.� Formatted for use in ArcGIS.
Map shows icons for businesses categorized as “Food and Drink” and those
with an ATM. Food and Drink records symbolized by type. The business footprint layer symbolized by category. Restaurants
are labeled with numbers (a table of names and details would accompany the map.) Facilities tagged recreation are labeled.
This map shows places that would be good to take a date. The records were individually selected by
adding a column to a spreadsheet and putting a “Y” by each business that I wanted to add on the map. The businesses were then symbolized to show type.
This map was created by the same method as the date-night map, but
this time, the selection was limited to places that are fun for kids. Parks were
added to the map.
Retail establishments can be categorized in many ways. This map uses a mixture of colored dots and
instructive icons. The points could be labeled or numbered.
Community maps can be:
� More Accurate� Local organizations manage the data.� Errors can be corrected easily.
� More control� Symbolize to highlight important information� Select what to include
More flexible� More flexible� Maps can be created in different formats (size, output, platform)� Data can be selected to meet differing requirements (parents, visitors on
Sunday, etc.)
� Better control of backgrounds� Can create own basemaps (roads, parks, rivers, etc).� USDA orthphotos (available free) typically better quality than GoogleEarth
photos,� Can use historic maps as background.� Can customize colors (monochrome/simple for easy printing, full color for web
applications and full color print.)
