Import Tree Survey File |
Design Suite: AEC > Existing Trees Landmark: Landmark > Existing Trees |
Survey file tree data can be imported into Vectorworks Landmark, and then used to automatically create existing trees with the proper attached information, including location. By mapping the attached data to the existing tree parameters and to record fields, valid existing tree objects or survey areas containing existing trees are created in the file with all the survey data incorporated. After modification, data from an existing tree schedule can then be exported as a tree survey text file.
If importing geographical coordinate data (or survey areas) with latitude/longitude information, set up georeferencing for the file first. Use an appropriate coordinate system for the data. See Specifying document georeferencing.
If desired, loci with attached record data can be created instead. The loci with the tree information can then be exported in shapefile format.
To import existing trees from a survey file:
Select the command.
Select the survey file to import.
The Import Tree Survey dialog box opens. Specify how to import the tree survey data and how to map the data to the existing tree parameters in the Vectorworks file. The settings can be saved for future use.

Saved Settings Options |
See Using saved sets to save and apply saved settings |
|
Survey File Format |
Specifies the File Type of the import file: Excel: .xls or .xlsx file; if the spreadsheet contains multiple sheets, the first sheet will be imported Tab delimited: File with tab delimiters between fields Other: File in any other format; also enter the Delimiter Character that separates the fields |
|
Survey Data |
|
|
Data Starts at Row Number |
Indicates the row where the survey data starts listing the existing tree information (this allows extraneous information such as author, title, and so on to be ignored) |
|
Data Has Column Headers |
If the survey data contains a header row, select this option, and then do not count the header row when entering the row number where data starts. The header rows, if they exist, are listed for each row of the Survey Column in the Survey Mapping data; if they do not exist, the Survey Column rows are numbered sequentially. |
|
Create Custom Record with Name |
In addition to mapping the data to existing tree parameters, a record format can be created and attached to the existing tree or the 2D or 3D loci that are created. When creating existing trees, this is useful for retaining all survey data with the objects. When creating loci, this allows all data to be retained for each locus. |
|
Survey Mapping table |
Each row in the table corresponds to a column in the tree survey file |
|
Survey Column |
If the data has a column header row, the headers are listed in the Survey Column rows; otherwise, the rows are numbered sequentially |
|
Parameter |
For each row, indicates the existing tree parameter that the Survey Column item is mapped to |
|
Unit |
For each row, indicates the unit that will be used at import. If the imported row contains text or entries which do not need a unit, leave the default selection of None/Automatic. If data can be imported with the specified document units, this will occur automatically with the selection of None/Automatic. If the imported data requires units that are different from the document defaults, select the unit to use for importing the data. |
|
Add to Record |
If creating a custom record to be attached at import, a check mark in a row indicates that the data for that row should be included in the custom record |
|
Selected Existing Tree Parameter |
Indicates how the selected row data should be mapped to its equivalent parameter at import |
|
Selected Unit |
Indicates the units for the selected row at import |
|
Import Options |
|
|
Create Existing Tree Objects |
Creates existing tree objects from the imported survey data |
|
Create 2D Locus Objects |
Creates 2D loci from the imported survey data (if the file is later exported as a shapefile, the loci within the shapefile are 2D loci). Only X/Y coordinates and any custom record information are imported when 2D loci are created. The remaining existing tree parameters are not included, even if they are mapped. |
|
Create 3D Locus Objects |
Creates 3D loci from the imported survey data (if the file is later exported as a shapefile, the loci within the shapefile are 3D loci). Only X/Y/Z coordinates and any custom record information are imported when 3D loci are created. The remaining existing tree parameters are not included even if they are mapped. |
Select each row of the survey mapping table, and then specify how it should be mapped to the equivalent existing tree parameter by selecting it from the Selected Existing Tree Parameter. If necessary, select the specific units that should be used if they’re different from the document defaults. If the row data should be added to a custom record, place a check mark in the row.
When mapping to existing tree parameters, the associated data values are mapped directly when the type is compatible. For example, when the height parameters are mapped, the height value from the survey file becomes the Height value for the existing tree; a mapped Condition parameter is set as expected if the entry matches one of the default options (Excellent, Good, Average, Poor), or to Custom if the entry doesn’t match the defaults.
When mapping georeferenced location data to the coordinate or latitude/longitude options, the import recognizes when the data in a row consist of a single entry, a pair of entries, or an array of double values.
X coordinate, Y coordinate, Z coordinate, and longitude, latitude require a single value from the survey data row, and each row creates a single tree.
A single pair of coordinates, enclosed in square brackets and separated by a comma, creates a single existing tree (or locus) for the XY coordinate, YX coordinate, latitude/longitude, and longitude/latitude pairs. For example: [10, 20]
Pairs of coordinates, enclosed within square brackets (with each pair enclosed in brackets and separated by commas), creates a 2D polygon representing a georeferenced area of existing trees for the XY coordinate, YX coordinate, latitude/longitude, and longitude/latitude pairs. Each pair of values defines the location of a polygon vertex. For example: [[10, 10], [10, 20], [20, 20]]
If no data are provided for mapped parameters, the default values of the Existing Tree tool are used.
There are some existing tree parameters for which there is no survey data equivalent; these parameters are also set to their defaults upon creation of the existing tree object.
Save the mapping settings if needed.
Click OK to import the survey data.
