  1. ArcMap Basics ESRM 250/CFR 520 Winter, 2010 Phil Hurvitz (with thanks to J. Lawler & P. Schiess) 1 of 49

  2. ArcMap Basics • Overview • Getting data into ArcMap • Displaying layers • Layer display properties 2 of 49

  3. ArcMap Basics • Overview • Getting data into ArcMap • Displaying layers • Layer display properties 3 of 49

  4. Getting data into ArcMap • Layer feature types • Spatial data sources for layers • Data frames • Adding a feature layer to a data frame • Adding a layer from x,y coordinates • Layer tables • Map document 4 of 49

  5. Getting data into ArcMap: Layer feature types • Vector Data • points (e.g., wells, utility poles, bird nests), • lines (e.g., roads, streams, utility lines), • polygons (e.g., cities, forest stands, PLSS sections, counties) • Raster Data • photographic, satellite, grids 5 of 49

  6. Getting data into ArcMap: Layers • Spatial data sources for vector data • ESRI geodatabases • ESRI shapefiles • ASCII files, database files • GPS output • And many many more • May require data conversion using ArcCatalog 6 of 49

  7. Getting data into ArcMap: Layers • Additional raster data sources for layers • ERDAS Imagine • Generic image formats • BSQ (band sequential), • BIL (band interleave by line), and • BIP (band interleave by pixel) • Sun raster files • BMP • Run-length compressed (RLC) files • JPEG compressed images • ArcInfo's image catalog • ArcInfo grid • Generic raster (ASCII, binary) • and more…. 7 of 49

  8. Getting data into ArcMap: Tables • Tabular data • Can be added to your map document • ESRI geodatabases • SQL (structured query language) database queries • dBase format tables • INFO tables • Comma or tab delimited ASCII (text) files • comma separated values (csv files) • tab-separated values or defined width (txt files) • OLEDB (object linking and embedding database) tables 8 of 49

  9. Getting data into ArcMap • A map document will always have at least 1 data frame (even if there are no layers present) 9 of 49

  10. add data button Getting data into ArcMap • Adding a data source to a data frame 10 of 49

  11. Getting data into ArcMap • All data sources are added in the same way ArcInfo coverage data CAD data 11 of 49

  12. Getting data into ArcMap • Adding a data source to a data frame • Icons indicate data type Polygon Line Table Point Raster 12 of 49

  13. layer is added Getting data into ArcMap • Adding a data source to a data frame symbology 13 of 49

  14. Getting data into ArcMap • Adding a layer from x,y coordinates • “event layer” • table must have X and Y value fields • Field names cannot have spaces 14 of 49

  15. Getting data into ArcMap • Adding a layer from x,y coordinates • points are added to the map document 15 of 49

  16. Getting data into ArcMap • Attribute tables • Feature ID • Shape • Geometry fields • Identification fields • User attribute fields • Entity fields 16 of 49

  17. Saving your work • Saving a map document (.mxd file) • Save EARLY and OFTEN 17 of 49

  18. ArcMap Basics • Overview • Getting data into ArcMap • Displaying layers • Layer display properties 18 of 49

  19. Displaying layers • Displaying layers • Why alter layer display? • What do you want to communicate? raw population population density 19 of 49

  20. Displaying layers: altering symbology 20 of 49

  21. Displaying layers: thematic mapping • Single symbol • A single symbol for each feature • Displays location/boundaries 21 of 49

  22. Displaying layers: thematic mapping • Unique value • Different symbol for each feature • Shows variation in value 22 of 49

  23. Displaying layers: thematic mapping • Graduated color = “choropleth” • Different symbol for each class • Displays groups 23 of 49

  24. Displaying layers: thematic mapping • Chart symbol • One chart symbol for each feature • Good for comparing multiple attributes in table 24 of 49

  25. Displaying layers: thematic mapping • Dot density • One dot for a number of individuals • For showing count/density for polygon data 25 of 49

  26. Displaying layers: thematic mapping • Graduated symbol • Graduated symbol size • Displays difference in magnitude 26 of 49

  27. Displaying layers • Classification methods 27 of 49

  28. Displaying layers: Classification methods • Jenks’ natural breaks • Classes are created with breaks at “natural” divisions in the data • Display inherent groupings orclumping 28 of 49

  29. Displaying layers: Classification methods • Histogram and statistics available 29 of 49

  30. Displaying layers: Classification methods • Quantile • Each class has about the same number of members • Good for uniformly distributed values 30 of 49

  31. Displaying layers: Classification methods • Equal interval • Divides data values into equal-sized subranges 31 of 49

  32. Displaying layers: Classification methods • Standard deviation • Classes show spread around the mean value • Displays variation in data mean 32 of 49

  33. raw population Displaying layers: Classification methods • Normalization of data • divides one field by another • shows percentage, proportion, or density population density 33 of 49

  34. Displaying layers: Manipulating classes • 10 classes 34 of 49

  35. Displaying layers: Manipulating classes • 3 classes with custom labels 35 of 49

  36. Displaying layers: Altering legends • Legends & symbology are controlled with layer properties 36 of 49

  37. Displaying layers: Changing symbology • Symbol selector • solid fill polygons; • single symbol for all polygons 37 of 49

  38. Displaying layers: Changing symbology • Changing symbology: polygons • different colors for: • fill • outline 38 of 49

  39. Displaying layers: Changing symbology • Predefined line symbols 39 of 49

  40. Displaying layers: Changing symbology • Predefined point marker symbols 40 of 49

  41. Displaying layers: Changing symbology • Fonts: • All installed TrueTypefonts are available 41 of 49

  42. ArcMap Basics • Overview • Getting data into ArcMap • Displaying layers • Layer display properties 42 of 49

  43. Defining layer properties • Defining layer subsets (definition query) • Setting scale thresholds • Labeling layer features 43 of 49

  44. Defining layer properties • Defining layer subsets • by default, layers are composed of all features 44 of 49

  45. Defining layer properties: Subsets • An underlying query(“filter”) can be applied only stands with age > 30 are shown 45 of 49

  46. Defining layer properties • Setting scale thresholds • allows layers to be displayed at specific scale ranges 46 of 49

  47. Defining layer properties • Setting scale thresholds • zooming willcause featuresto (dis)appear 47 of 49

  48. Defining layer properties • Labeling features 48 of 49
