Login Redirect Error Workaround

If Chrome is saying: "vector.geospatial.science redirected you too many times. Try deleting your cookies. ERR_TOO_MANY_REDIRECTS." after clicking the Login button, do the following to fix it.

Wait just a few seconds. 10 - 20, just to let the page finish re-directing you too many times.
Click on the little i on the left side of the address bar, to the right of the reload button. Mousing over the i button should show you a little popup that says "View Site Information"
In that dropdown menu, click on Cookies and Site Data
Click on Manage on-device site data
Trash all three items you see and click done.

Appendix A - Common File Types and Icons in ArcGIS

Vector
Polyline		A spatial file. Contains only polylines. Green= shapefile; Blue= feature class
Polygon		A spatial file. Contain only polygons. Green= shapefile; Blue= feature class
Point		A spatial file. Contains only points. Green= shapefile; Blue= feature class
Triangulated Irregular Network (TIN)		A vector representation of elevation the vertical distance between local mean sea level the measurement above or below the global average at a single point on the Earth's surface used for recording the elevation of topographic surface a detailed map of the surface features of land. It includes the mountains, hills, creeks, and other bumps and lumps on a particular hunk of earth. The word is a Greek-rooted combo of topos meaning "place" and graphein "to write." 's relief the difference between the highest and lowest point within a particular area while landforms are the descriptive words for individual features and a single point on the Earth's surface over a landscape
Network Dataset		Network Datasets are used to create complex analysis of transportation networks utilizing detailed attributes regarding how each feature interacts with the others. Green= outside geodatabase; Black= inside geodatabase
Raster
Raster (Image file)		Any image file. May or may not be associated with spatial data. Yellow= outside geodatabase; Blue= inside geodatabase
Organization
Geodatabase		The biggest “container” for spatial data. Can contain vector or raster data.
Feature Dataset		A container for similar vector files. Can contain points, lines, or polygons (not rasters).
Raster Catalog		Collections of rasters which are organized and defined by a key. Can not contain vectors.
Topology		A GIS topology is a set of rules and behaviors that model how points, lines, and polygons share coincident geometry.
Tables
Excel Table		Excel table. Contains non-spatial data. Often is ‘joined’ or ‘related’ to spatial data.
Other Data Table (various kinds)		Tables without the specific .xls file extension. May contain non-spatial numeric or text data, or may contain numeric data associated with a spatial object. Tables are not specifically spatial, but often make up a crucial part of spatial data.
Other Icons
Text File		Text files are used for any sort of textual or paragraph data storage, such as metadata (information about the spatial data) or methods/other notes. While ArcGIS can read text files, they do not serve any sort of analysis purpose for us.
