v0.1.5

This release adds error handling to the RAS MCAT for older RAS models (version < 4.0) that do not contain geospatial data. This error handling includes code to check:

• the geometry file version when determining if the model is geospatial.
• that the model is geospatial before trying to extract the geospatial data itself.
• if a cross-section's cutline is actually extracted from the geometry file.
• if there are two or more station elevation pairs per cutline.

v0.1.4

This release includes updates to the isamodel, index, and isgeospatial methods.

• The passed S3 key is said to be a model if the key is a .prj file, which exists and is valid, and if there is at least one geometry file in the same directory as the .prj file.
• The index method now returns the general MCAT Model struct instead of the RasModel struct.
• A model is said to be geospatial if it is a model and if a valid projection is identified.

v0.1.3

This release uses the most up to date version of filestore, which updates the S3FS ping method. If a user enters the incorrect credentials or the name of a bucket that does not exist, the ping will return an error, otherwise the error will be nil.

v0.1.2

This release updates the name of one of the fields in the cross-section vector layers from "InterpolatedLine" to "CutLineProfileMatch." This change is to make the field more descriptive, where the field indicates whether a cut line and the cross-sectional profile match, i.e. whether they have the same length.

v0.1.1

This release addresses edge cases that were identified during testing. Updates include:

• a print statement to notify the user of two or more .prj files in the same directory when the second .prj is not a valid projection file.
• stripping of non-numeric characters from a cross-section's station to avoid parsing errors.
• a test that compares the length of a cross-section's 2D cutline to its profile length in order to avoid building a 3D cross-section linestring from station elevation data that does not match the cutline geometry.

Initial Release

This is the initial release of the HEC-RAS Model Content and Analysis Tool (MCAT). The HEC-RAS MCAT is a stand-alone micro-service which includes its own REST API as well as a suite of methods called using HTTP requests for interrogating a HEC-RAS model. Included in this release is the capability to extract information from 2D models and information on hydraulic structures.
