Leica Infinity：功能编码
有限元分析是什么ture coding?
When surveyors collect field data, they document the position and details of requiredfeatures。一切都可以视为一个功能：建筑物，围栏，道路，长凳甚至树。进行测量时，测量师通过输入代码和属性记录了功能的细节，这些代码和属性存储在测量点中。
The代码categorise and identify the feature, describing what it is in the field; for example, a single point can be coded to represent a tree or gully and few points can be coded to represent a road or fence. A special code property called linework is used to join the points with a line to create a linear feature like a building or wall.
Attributesare linked to a code and are used to describe the feature and give additional details. For example, if your coded feature was a wall, the attributes you use might include its material type, height or width.
Using feature coding saves time and increases productivity both in the field and the office by having features described and for visualizing the data in the software. This is helping with QC of collection of features and help the data processing step before sending data to CAD or GIS solutions.
The typical feature coding workflow in Infinity
Working with feature coding requires some data preparation and processing in the office before and after measuring in the field. The typical workflow is:
预先定义代码和功能样式库– first the user must create the Code table which is managing the list of codes, attributes and styling information used to assign to measured data. The table is applied to data imported or created in a project.
Creating a codelist– from the Code table the user can export a codelist to use in with the field software Captivate, Viva, System1200, iCON and Zeno
Creating a codelist– from the Code table the user can export a codelist to use in with the field software Captivate, Viva, System1200, iCON and Zeno
数据采集– the codelist is transferred to the field software and it should be used to define features with the measurements in the field job.
办公室数据处理– the collected data is imported into an Infinity project with the coded features. The code table applies automatically the correct style to the imported field data.
This workflow describes all the steps for efficient field collection. Using feature coding makes verifying the job easier in the office. To support individual customer’s visual styles, a user can create several different Code tables using the same library of codes but apply different feature definitions and styles.
Using Code tables in Infinity
How using Code tables in Infinity supports the whole process of feature coding?
使用代码表创建编码师
在进行现场工作之前，创建一个编号师不是强制性的，但是在现场软件中进行实地专家可能会耗时且尴尬，而功能有限。最好的做法是预先定义适合工作类型的代码列表。所有现场工作人员都应使用相同的编码人员。
When creating a code, the user defines the type of the code and a style for the linear features. Infinity supports all types of codes including points, lines, areas and free codes used by the existing System 1200 and Leica Viva users.
有两种用于特征编码的方法：分配给点，线和区域或免费代码的主题代码。自由代码与主题代码不同，因为它们纯粹是与时间相关的信息，并且在现场测量之间记录了。记录了每个免费代码的时间戳，允许按时间顺序排列的导出点和免费代码用于第三方映射软件。
For each code, the user can enter one or more attributes and define if they shall be automatically prompted to enter it. An attribute can be defined in many ways, for example, as a simple text field, a choice list, a range to choose from or a default value.
The user does not necessarily need to create a codelist from scratch as they can use existing data to automatically populate a new library of codes. This can be done by importing an existing codelist, a Leica DBX job, FlexLine CLS file, ESRI geodatabase or HeXML file.
在Infinity中使用代码表的好处如下：
- 快速有效地创建代码库
- 重新组织，更新或加入代码列表的简便方法
- The same codes can be exported to different instruments types or formats
- 用户之间可以轻松共享代码表

使用代码表来样式功能
当创建绘图CAD软件,一个手术or uses geometry objects to represent features. For example, a certain CAD block represents a tree or a signpost or a special line style is used to distinguish between road and a kerb. The operator also defines similar styles for related features, and groups them on the same layers allowing fast modifications to be made to the whole group of features.
Infinity会在数据导入期间自动应用所需的编码样式。这意味着用户可以以已与已完成后直接的直接可交付的格式查看数据。
How can the Code table be set up to provide the styling? The user can import a pre-defined CAD file with all the required layers, blocks and line styles. The layers and blocks can be extracted from a DXF/DWG file. The layers can be used so that the coded features are grouped together using the same style.
一个块可用于用简单的几何对象表示功能。这包括2D或3D功能。通过将块分配给代码，代码属性可用于扩展块以在其真实的相对大小中表示该功能。例如，该属性可用于缩放树块，以便正确绘制冠层大小。
The line styles can be imported from the .LIN files, this way a line can be represented as a pattern of dashes, dots, text or symbols.

无穷大的功能处理
无穷大的功能处理is a straight forward task. User just needs to create a project, attach a Code table and import the data. In the 3D view, the points are automatically plotted with the blocks, the lines use the defined style and the features belong to the assigned layers.
Once a Code table is attached to the project, the entire content, including the code and style information, is included in the project. This means that if the project is transferred to another user, there is no need to provide additional files. If the position of the data in the project needs to be updated due to any processing tasks like GNSS or TPS processing, the features will be updated automatically without the need of further re-processing.
如果用户需要在项目中编辑代码，则可以使用项目代码管理器进行此操作，在该项目代码管理器中可以找到代码管理器中可用的相同编辑功能，例如能够编辑层，块和行样式。但是，项目代码管理器中进行的任何编辑仅适用于当前项目，并自动更新项目中的数据。
在项目代码管理器中，用户还可以看到该字段中创建的任何新代码。新代码可以轻松合并到代码表的代码和样式中。
Infinity提供了一系列工具，允许用户纠正任何数据问题。问题可能是由于编码不正确，在观察功能时键入错误或障碍物。一些示例是，当未分配到一个点或输入错误的属性或测量错误点时。
The feature editing menu contains options to Join, Break, Delete, Split or Curve line features. Missing features can be easily added by creating new points, lines and assigning codes.
Thematic features can be easily exported to CAD software. Before an export, the user can define in the Layer Manager which survey and thematic layers must be sent to CAD. The export settings can be saved to a template file for future references. Afterwards the data and features can be exported by selecting *.dwg or *.dxf format type.
