In this lecture we’ll consider how space is most commonly conceptualized in GIScience (e.g., fields and objects\/entities) and how those concepts are implemented as GIS data models (and the advantages and disadvantages of the two fundamental models of space–grids or rasters and vectors); basically, how is geography represented in a GISystem?<\/p>\n
\u00a0In this short paper (scroll down for text!)<\/a> Antony Galton provides a theoretical review of the conceptualization of objects and fields, while in GIS Basics: Chapter 4<\/strong> (Data models for GIS; links below) the discussion is centred around the implementation of models of space in a computer. You could say that Galton presents the GIScience<\/strong> perspective while Chapter 4 presents the GISystems<\/strong> perspective.<\/p>\n It is important to recognize that your conceptual<\/em> view of the world should be independent of the programmatic<\/em> view of the world. That is, how we conceptualize things should not be constrained a priori<\/em> by how things are represented in the computer.<\/p>\n \n<\/div>\n [Slides]<\/a><\/p>\n Text: <\/strong>Chapter 3: Representing Geography<\/a><\/p>\n <\/p>\n Alternative text<\/strong>: GIS Basics: Chapter 4<\/a> although this material is only directed at the implementation models (i.e., raster and vector), and does not discuss the conceptual models (i.e., objects and fields).<\/p>\n In this short note<\/a> Goodchild describes both the GIScience perspective (objects and fields) and the GISystems perspective.\u00a0 Also, again, Antony Galton's short paper (scroll down for text!).<\/a><\/p>\n Chapter 2 (especially section 2.1) of the online text Geospatial Analysis<\/a> also provides a thorough overview of the basic primitives of geospatial data. (If you are thinking of becoming a GIS Analyst, you should bookmark this online text<\/strong>.)<\/p>\n Chapter 4: GIS and network analysis in GIS and the Social Sciences<\/a> by Dimitris Ballas, Graham Clarke, Rachel S. Franklin and Andy Newing provides a very easy to follow introduction to network analysis. (If you are a human geographer interested in GIS, you should bookmark this text<\/strong>.)<\/p>\n Here is a link to WKIDs (spatial references) that ESRI and QGIS use to identify projections<\/a>. Many programs, such as QGIS, use WKIDs as the primary means of identifying the projection\/coordinate system, so it useful for you to know what they are and where you can look them up.<\/p>\n<\/div>\n ESRI has a tutorial on how to use the Network Analyst for ArcGIS Pro<\/a>.
