2. Created by Yafang Su at UCLA- Academic Technology Services Creating point features from table Three Ways: In ArcMap: 1. Tools/Add XY data 2. Add Data, then Right click and choose Display XY data. In ArcCatalog: 3. Right click and choose Create Feature Class/From XY Table.

3. Created by Yafang Su at UCLA- Academic Technology Services Address Geocoding Two datasets: –an address event table –a reference data source. A reference data source can be any polygon, point, or line feature class that contains the necessary address attributes.

4. Created by Yafang Su at UCLA- Academic Technology Services Address Matching The formula is ((Candidate address - minimum address) / range). In the example, ((824-800) / 98) or (24/98), which is 0.245, or 24.5%.

5. Created by Yafang Su at UCLA- Academic Technology Services Geocoding Service Single Field: Use one key field to match US Streets with Zones: Two numeric ranges left and right side, with left and right zones (city names or zipcodes) Zip 5-Digit: Five Digit Zipcode

6. Created by Yafang Su at UCLA- Academic Technology Services Output Feature Class All the attributes from the address table + 3 new fields: Status: “M”, “U” or “T” Score: 0-100 Side “L” or “R”

7. Created by Yafang Su at UCLA- Academic Technology Services Buffer Wizard Buffer from selected features. Use a layer's attribute to determine the buffer distance. Create multiple ring buffers using a fixed distance, for example, 50, 100, and 150 meters Change distance units interactively. Buffer inside, outside, or inside and outside polygons using a set distance. Buffer a set distance outside polygons and include the interior of the polygon in the output. Dissolve contiguous buffers into a single feature or create individual, overlapping buffers for each feature being buffered.

8. Created by Yafang Su at UCLA- Academic Technology Services Geo-processing Wizard 5 Functions: Dissolve Merge Clip Intersect Union

9. Created by Yafang Su at UCLA- Academic Technology Services Output Coordinate system: same as the data frame (one exception save as a feature class of GDB) Attributes –Shapefile: no area, perimeter or length –Feature class in GDB: Polygon: area, perimeter, length Line: length Point: no
