Fundamentals-of-GIS
The document provides information about three GIS technicians - Bre Callear, Collin King, and Jordan Carmona - and their experience levels. It then covers best practices for naming files and folders in ArcGIS projects, how to address issues like slow performance from cache bloat, and tutorials for different editing tools in ArcMap including cutting polygons and merging data. The document aims to teach readers good file organization and data management techniques as well as tips for using common editing tools.

- 3. Naming Files forUse in ArcMap Naming MXDs Folder structure MXD Bloat How it happens How to fix it Editing Navigating ArcMap editing A quick deed plus clean up Editing Tools Cut, merge, EXPLODE, and more!
- 4. Naming in MXDs Creatingmeaningful layer names Field name, Do’s and Don’ts Folder Structure and Data Management Why names matter What not to do How to structure your GIS folder MXD stands for Map Explorer Document
- 5. Creating Meaningful LayerNames A layer’s name should describe it succinctly Avoid jargon Avoid numbers
- 6. Field Names, Don’t’s Jargon Numbers SpecialCharacters Spaces, !@#$%^&*() Cannot begin with a number or _
- 7. Field Names, Do’s Afield’s name should describe it succinctly Right Field for the Right Data Integer, Float, Text, and Date
- 8. Folder Structure andData Management Organization and optimization for standard operating procedures When correct folders are closer together everything runs faster Let’s go over the good, the bad, and the ugly of folder structuring
- 9. The Ugly Everything isnamed the same Everything is still named the default settings Everything is all in the same folder
- 10. The Bad DifferentNames for Different Items, Not Specific Some Folders, but Not Enough Multiple MXDs, Vague Names
- 11. The Good Specific namesfor specific files Concise, legible An intelligent folder structure Archive, MXDs, shapefiles, misc. Multiple MXDs, templates
- 12. What happens Running slow Howit happens Caching How to fix it Caching is when data is saved for ease of access
- 13. The twomain culprits are: Image cache MXD bloat Running Slow? An overly large cache can cause ArcMap to run sluggishly
- 14. Growth in Action! To follow: How the image cache grows How the MXD grows
- 15. How the ImageCache Grows Video
- 16. How the MXDGrows Video
- 17. Let’s Fix It! To follow: How to clear image cache in ArcMap How to clear MXD cache
- 18. How to Clearthe Image Cache in ArcMap
- 19. How to Clearthe MXD Cache
- 20. Navigating ArcMap editing Createfeature Attributes Traverse Building and placing a deed Building a deed Placing a deed Topology edits Saving edits
- 21. Create Feature Window Shows the editable layers that are turned on Sets up the editing environment based on the feature templates properties
- 22. Attribute Window Displaysattributes of selected features Allows you to edit the values TIP: Data from CAMA that BIS receives is read only, so we can not edit legal information
- 23. Traverse Create/edit/sketch geometry fromdifferent types of measurements Add or subtract segment/curve as a line in the traverse course table Next Up: draw and place
- 24. Traverse From aPlat Video
- 25.
- 26. Saving Edits Save early,save often If you don’t save, it doesn’t exist
- 27. Topology Allows youto move multiple layers at once Keeps your data clean and fast
- 28. Let’s create acustom tool bar and add the following tools: Cut polygon Planarize lines Merge Explode Rotate Split We will discuss each in detail
- 29. How To MakeA Custom Tool Bar
- 30. Cut Polygon Updatesthe shape’s existing feature Creates one or more new features TIP: Be sure you have completely intersected the feature for a successful cut
- 31. Planarize Lines Splitsselected lines where they intersect
- 32. Merge Combines multipleinput datasets of the same data type into a single output dataset Can combine point, line, or polygon feature classes or tables TIP: Data does not need to be touching to be linked together
- 33. Explode Separates aselected multipart feature into individual component features TIP: Useful if you need to alter the attributes in one of the elements in a multipart feature
- 34. Rotate Reposition tothe desired orientation TIP: Holding the “A” key you can specify the rotation angle
- 35. Split Splits aline feature into two parts at any point TIP: If two roads are crossing, you can use intersection snapping to precisely locate the point to split
- 36. Summary You areready to nerd out to: Good data structures within ArcMap and your computer’s folders Cache and MXD bloating Types of editing and basic tools Ready to nerd further? Check out our demonstration lab! Nerd your way through all of our class material
