Steps for a project:
The first step is to convert a question.
The next step is to create a database that contains the
geographic data required to answer the question. This may
involve digitizing existing maps, obtaining and translating
electronic data from a variety of sources and formats, making sure the layers are of adequate quality for the task,
making sure the layers are in the same coordinate system
and will overlay correctly, and adding items to the data to
track analysis result values.
The next step is to analyze the data. This usually involves
overlaying different layers, querying attributes and feature
locations to answer each logical part of the question,
storing the answers to the logical parts of the question, and
retrieving and combining those answers to provide a
complete answer to the question.
The final step in a project-based analysis is to
communicate the results of the analysis, usually to people
who do not use GIS and who have different levels of
experience in dealing with maps. Maps, reports, and graphs
are all used, often together, to communicate the answer to
the question.
