SPATIAL ANALYSIS - Word Document Summary available
ArcView Functions most commonly used for Spatial Analysis

• ID Tool
• Query Builder
• Select By Theme (theme-on-theme selection)
• Convert to Shapefile
• Buffer
• Charts
• Legend Editor
• Summarize
• Field Statistics
• Spatial Join

	point	line	polygon
point	nearest	nearest	inside
line	nearest	part of	inside
polygon	n/a	n/a	inside

Single Layer Operations - Horizontal

• Feature Identification and Selection
• Feature Classification
• Feature Manipulation

Multi-Layer Operations - Vertical

• Overlay Analysis
• Multi-Layer Proximity
• Simple Correlation Analysis
• Frequency/Density

Point Pattern Analysis

• Nearest Neighbor Index
• Quadrat & Poisson
• Spatial Autocorrelation

Network Analysis

• Diad Analysis - distance from x to y
• Minimal Spanning Tree
• Shortest path
• Traveling Salesman problem
• Shipment problem

Surface/Raster Analysis

• Vector Surfaces (contours, TINs)
• Global Approximation (Interpolation)
• Map Algebra - Local, Focal, Zonal, Global Operations
• Diffusion Modeling
• Connectivity
• 2.5D Imaging
• 3D Imaging

Modeling

• Trend Analysis
• Multiple Regression
• Significance Tests
• Logistic Regression

Spatial Data Import/Export/Exchange/Conversion
Spatial Data on the Web

• Static Maps
• Internet Map Servers - snapshots of dynamic maps
• Spatial Data Servers & ArcExplorer - Dynamic Maps
• Downloading spatial data
  • compression - data is often zipped or tarred - Use WinZip or PKUnzip to unpack
  • vector data in Arc/Info export format (*.e00) - Use the Import71 utility that is packaged with ArcView (not inside the software; it is a separate utility)
  • vector data in DXF format - can usually import directly to AutoCAD, Microstation or ArcView - but no attribute tables
  • ALWAYS look for METADATA - information about projections, units, resolution, coverage, etc.
    
    
  Some Common Interchange Formats
  

  Extension	Native Software	To bring into ArcView
  *.E00	Arc/Info Export format	Import71 Utility
  *.DXF	AutoCAD exchange format	CadReader extension
  *.DWG	AutoCAD drawing files	CadReader extension
  *.DGN	Microstation design files	CadReader extension
  *.MIF	MapInfo format	MIF2SHP script or Mif2Shp Utility
  SDTS	Spatial Data Transfer Standard	new interchange format - see USGS website for details
  *.DBF	dBase/FoxPro	no import required
  tab delimited	generic database	File > Import menu item
  comma delimited	generic database	Import to Excel, FoxPro or Access, Save As *.DBF
  space delimited	generic database	Import to Excel, FoxPro or Access, Save As *.DBF
  fixed length	generic database	Construct table in FoxPro or Access, Append, Save AS *.DBF
  *.TIF/*.TIFF	raster	Add Theme > Image Data Source
  *.JPG	raster	JPEG Image Support Extension
