algorithmic modeling for Rhino

Information

@it

'@it' is a free GIS plugin for Grasshopper to parse the geospatial data sets. The plugin @it aims to leverage Open Data, to allow user to make quick visualization to reveal the invisible dimensions, relationship, patterns and trends. 

The main feature is GIS data visualization utilizing spatial data sets in .shp (shape) format. There are three components for the spatial data visualization feature:

shp@it category includes generic GIS tools; supports Point, Line, Polygon vector data format

  • Feat@it: is a look-up component. Input .shp file, Outputs the list of attributes (features) in the given data set and the type of vector data set
  • Import@it:  imports to data into as Grasshopper objects that makes easier to query. Input .shp file, Outputs the shape items as system objects [this component organizes the contents of the data set into system.objects]
  • DataVis@it: Visualizes and filters the data set, input the objects from Imp@it components. Outputs the curves, points, and related filtered attributes.

IshpNYC: These are the NYC specific GIS tools (Open Data, .shp files)

  • Footprint by Borough: Sorts the footprint data set of NYC buildings by borough. 
  • Data Binding: Binds two NYC data sets per common attribute; utilize NYC Tax property and Footprint vector data sets. Outputs shape object has combined attributes and geometry.
  • NYCVis: Visualize and filter the data set, input the objects from Data Binding components.

GeoCoder: Uses Google map api (no plugin needed but u need internet connection)

  • Address Parser: Parses the bad address, returns the formatted addresses and location (latitude , longitude)
  • Street View: Uses Coordinates (latitude , longitude) address parser and return the static street view on the active viewport. 
  • [new] Address Lookup: Reverse Geocoding, returns formatted address from Coordinates (latitude , longitude)

[new] Statistics :

  • [new]Coordinates2Statistics: Uses Coordinates (latitude , longitude) and returns Statistics of specified place such as Population, Elevation, land cover etc.

[new] Open Street Map OSM: Components to parse OSM data, utilizes REST api

  • [new] osm_Trace : Traces OSM and returns features. Projection types UTM or WGS84 
  • [new] osm_3D_Bldgs: Returns 3D geometry of OSM buildings, uses UTM projection and draws in Rhino model units.
  • [new] osm_Bldg_Info: Parse geojson data of OSM buildings, returns features/or tags.

shx to shp conversion?

I have a .shx file only for my city but no .shp file.  Is there a way or a tool that can convert the .shx file to .shp?Thanks. Continue

Hi Grasshope, 

Sorry for the later reply. Yes there is a bug on the shape files importer, likely has a very easy fix. I would like to add more revisions to new version that is why it has been took a while.

I will try to see whether I can do it at this weekend.

Thank you for reporting the issue. cheers

I'm not sure if Elcin is available now. But can anybody with experience of using the @it GIS components advise on the issue I encountered as posted here: SHP file with only one feature cannot be read correctly?


Thank you very much!

Comment by Grasshope on November 16, 2016 at 10:07pm

Hi, Elcin,

It seems the @it import SHP component is unable to read shape file containing only one polygon.

 

The attached test_b.shp file contains only one polygon and test_b2.shp has two polygons.

 

However, only the test_b2.shp file can be read correctly by the @it import SHP component.

 

Can you kindly help to check and confirm this issue?

 

Thank you!

Elcin,

Thanks so much, I understand now.  I'll see what I can locate from the administrator.

Best Regards.

Hi Mark,

.shx file is an index file which is one of the dependency file of the shape file. You need main .shp file to parse, .shx itself doesn't contain data. 

Shape file is composed of minimum of these three files below, the prefix has to be the same. see example.

Main file: counties.shp

Index file: counties.shx

dBASE table: counties.dbf

I suggest check your source again whether the main file might be forgotten. Hope this helps, please let me know

PS: I am almost done with the components that parses geojson file types (other very common gis data type) and converts shape files into kml (google map files)

Hi Elcin,

I took a workshop from you at The University of Cincinnati last fall which was great, and I'm starting to use @It more and more.  

I'm wondering if there is a SHX to SHP conversion tool or converter that you know of?  I have several SHP files for different aspects of my city but the master file (which has all the information) is only in SHX format.

Thanks.

Comment by Elcin Ertugrul on April 27, 2016 at 3:41pm

Thank you Guillaume, well the bottom component is the last one but apparently I forgot to add last bool input for the projection conversion.

Yes you can do simple extrusion witch using height attribute, but what I was doing differently is parsing more detailed building masses from OSM buildings database. OSM_3D buildings component parses different roof shapes such as sloped roofs or towers etc. seen as http://osmbuildings.org/?lat=40.73555&lon=-73.9891&zoom=17&...

I will make revisions and upload Food4Rhino asap. Thank you again for reporting the bug, it is a good catch.

Cheers.

Comment by Guillaume Meunier on April 27, 2016 at 2:26pm

BTW there is a small bug

as you can see, the osm-trace on top as a boolean instead of a numeric for lon_r.

I don't know which one of osm-trace is the last one

Here is my script that create 3D without OSMbuildings

Enjoy

Hi Elcin,

the comment you posted did not had to do something with my problem. I allready had the problem before the OSMbuildings server went disabled. When using shapefiles, the same message kept bugging me. not only on this plugin but HERON told me it as well. a few days ago i stumbled upon an answer. My units in Rhino were set in centimeters instead of meters. i guess this was the problem because the components are working just fine right now.

thanks for your help and im curious for the new release with enhancements!
