Shape Editor application,
you can view and edit any of the lines and polygons you
may have added while you were entering observations.
You can also enter a new line or polygon.
You can also upload a polygon shapefile,
so that the polygons in the file become available for search
in Observation Hotline and What Grows Here?.
As a Calflora contributor, you have your own portfolio of lines and polygons. Each time you enter an observation record with a line or polygon, the line or polygon goes into this portfolio. Each time you make a search polygon from Observation Hotline or What Grows Here?, and save it by name, it goes into this portfolio.
If you are a member of a group, then any lines or polygons associated with the group will also be available to you through this application. You can also share your polygons with a group.
A line or polygon stored by this application has only the following
If you upload a shapefile of lines or polygons with this application you will be able to choose a single attribute from the shapefile to become the name of the line or polygon as it resides on Calflora. Other attributes will be ignored.
If you have a shapefile with plant observation data in it, and you want to load the observations into your Calflora account, this is not the right application to use. If will be much easier to upload a shapefile of observations into your Calflora account if you use the Observation Upload application instead.
Please contact Calflora support with any questions about using this application.
|Editing a Shape Record|
To select a record, click on the
in the leftmost column. The line or polygon appears on the map, and
a panel opens up showing the details of the record.
In the detail panel, press to edit the record.
|Editing the Line or Polygon|
Press to change the line or polygon.
When editing, the vertices appear on the map as follows:
The first vertex appears as a white diamond,
If you are editing a polygon, the inside of the polygon is colored purple. You can change the map zoom level, or re-position the map by dragging, while you are editing.
Drag a vertex to move it. Click directly on a vertex to delete it.
To add a new vertex, click on the map. The new vertex will be inserted
in between the closest two existing vertices. If the new vertex does
not go where you expect, delete it, and try clicking very close to an existing vertex,
and then dragging the new vertex to where it belongs.
To delete many vertices at once, check
Press to delete all vertices within the rectangle.
Here are some examples of polygons generated from lines.
Note the holes in 2C. below, when the value of Buffer is 6.
|Adding a Shape Record|
To add a new record, press
Click on the map to add vertices.
The first vertex appears as a white diamond,
Drawing a Line. Each new click on the map adds a vertex to the end of the line.
Press when you are done.
Press to delete vertices or add new vertices.
Press to save the new record.
Note that if you have a shapefile containing plant observations,
this is not the right application; if will be much easier if you use
Observation Upload instead.
contact Calflora support with any questions.
To upload a shapefile from your local computer, open
In Step 1, browse to find the four component files
of a shapefile. (Note that the .prj file is
necessary, and that .prj files are sometimes hidden on Windows systems.)
|When the upload is successful you will see this message:|
In Step 2, you assign values to the new polygon records.
You will see a few lines from the shapefile showing the available
attributes. Choose which attribute should become the
name of the polygon in your Calflora portfolio.
You can also choose to associate all of these polygons
with one of your groups. You can also assign a purpose for each polygon.
In the example on the right, the available attributes from the shapefile are LAYER, COUNT, CNPS, CHPTBNDA_, and CHPTBNDA_J. In this case, the user chose the attribute CNPS to become the name of the polygon -- by looking at the records in the table, you can see that this attribute has values like Dorothy King Young and Sanhedrin.
In this case, the user chose "search" as the value of Purpose, so that these polygons will be available for searching from applications such as Observation Hotline.
If you are planning to use the uploaded polygons in observation records, then set Purpose to "assessment", and they will be available from the Plant Observation Entry application.
Once you have assigned values, press .
When the records have been added, you will see this message:
To find the records you just added, use the search function of this application.
|After you have searched for some shape records, you can download them to your computer, and then use them in desktop GIS. At the moment the only supported format is GeoJSON. If you need the shapes in a shapefile, download them as GeoJSON and then use QGIS to convert them to a shapefile.|
|The Purpose Attribute|
Each shape record can have one of five possible purposes:
March, 2019: In v. 1.09, when you are editing a shape, there is a new Select vertices by rectangle function. You can use this function to delete many vertices at once.
January, 2018: In v. 1.00, the generate a polygon function has been improved, and is now available with buffer values from 1 meter to 20 meters. Note that it can take a long time to run, more so with a large original line and/or a small buffer value.
September, 2017: As of v. 0.98, you can search by geometry type (eg. line polygon etc).
June, 2017: As of v. 0.95, this application can display multipolygons and polygons with holes. However, it is still possible to edit only simple polygons and lines.
July, 2016: As of v. 0.86, the editor panel opens under the selected record, instead of at the top of the page. Also, the vertice count of the selected shape is displayed.
December, 2015: As of v. 0.70, the shapefile uploader takes up more room on the page, so that it is easier to see the attributes.
August, 2014: As of v. 0.60, this application has the ability to upload a shapefile. The polygons in the shapefile can become part of your personal portfolio of shapes, or part of your group's portfolio of shapes.
REGION is a new possible value for purpose.
August, 2014: v. 0.59 (beta) released.
