Create LAS Dataset

Creates a LAS dataset referencing one or more LAS files and optional surface constraint features.

ينشئ مجموعة بيانات LAS تشير إلى واحد أو أكثر من ملفات LAS وميزات قيود السطح الاختيارية.

1.    Input Files ملفات الإدخال

The LAS files and folders containing LAS files that will be referenced by the LAS dataset.

In the tool dialog window, a folder can also be specified as an input by selecting the desired folder in Windows Explorer and dragging it into the parameter's input box.

ملفات ومجلدات LAS التي تحتوي على ملفات LAS والتي سيتم الرجوع إليها بواسطة مجموعة بيانات LAS.

في نافذة حوار الأداة ، يمكن أيضًا تحديد مجلد كمدخل عن طريق تحديد المجلد المطلوب في مستكشف Windows وسحبه إلى مربع إدخال المعلمة.

2.    Include Subfolders (optional) تضمين المجلدات الفرعية (اختياري)

Specifies whether LAS files residing in the subdirectories of an input folder will be referenced by the LAS dataset.

· Unchecked—Only LAS files found in an input folder will be added to the LAS dataset. This is the default.

· Checked—All LAS files residing in the subdirectories of an input folder will be added to the LAS dataset.

يحدد ما إذا كان سيتم الرجوع إلى ملفات LAS الموجودة في الدلائل الفرعية لمجلد الإدخال بواسطة مجموعة بيانات LAS.

• غير محدد - ستتم إضافة ملفات LAS الموجودة في مجلد الإدخال فقط إلى مجموعة بيانات LAS. هذا هو الافتراضي.

• تم التحديد - ستتم إضافة جميع ملفات LAS الموجودة في الدلائل الفرعية لمجلد الإدخال إلى مجموعة بيانات LAS.

3.    Output LAS Dataset إخراج مجموعة بيانات LAS

The LAS dataset that will be created.

مجموعة بيانات LAS التي سيتم إنشاؤها.

4.    Surface Constraints (optional) قيود السطح (اختياري)

The features that will contribute to the definition of the triangulated surface generated from the LAS dataset.

· Input Features—The features whose geometry will be incorporated into the LAS dataset's triangulated surface.

· Height Field—The feature's elevation source can be derived from any numeric field in the feature's attribute table or the geometry by selecting Shape.Z. If no height is desired, specify the keyword <None> to create Z-less features whose elevation would be interpolated from the surface.

· Type—Defines the feature's role in the triangulated surface generated from the LAS dataset. Options with hard or soft designation refer to whether the feature edges represent distinct breaks in slope or a gradual change.

Surface Feature Type—The surface feature type that defines how the feature geometry gets incorporated into the triangulation for the surface. Options with hard or soft designation refer to whether the feature edges represent distinct breaks in slope or a gradual change.

· anchorpoints—Elevation points that never get thinned away. This option is only available for single-point feature geometry.

· hardline or softline—Breaklines that enforce a height value.

· hardclip or softclip—Polygon dataset that defines the boundary of the LAS dataset.

· harderase or softerase—Polygon dataset that defines holes in the LAS dataset.

· hardreplace or softreplace—Polygon dataset that defines areas of constant height.

الميزات التي ستساهم في تحديد السطح المثلث الناتج من مجموعة بيانات LAS.

• ميزات الإدخال - الميزات التي سيتم دمج هندستها في السطح المثلث لمجموعة بيانات LAS.

• حقل الارتفاع - يمكن اشتقاق مصدر ارتفاع الميزة من أي حقل رقمي في جدول بيانات المعلم أو الشكل الهندسي عن طريق تحديد Shape.Z. إذا لم يكن الارتفاع مطلوبًا ، فحدد الكلمة الأساسية <None> لإنشاء ميزات Z-less التي سيتم إقحام ارتفاعها من السطح.

• النوع - يحدد دور الميزة في السطح المثلث الذي تم إنشاؤه من مجموعة بيانات LAS. تشير الخيارات ذات التعيين الثابت أو الناعم إلى ما إذا كانت حواف الميزة تمثل فواصل مميزة في المنحدر أو تغييرًا تدريجيًا.

نوع ميزة السطح — نوع ميزة السطح التي تحدد كيفية دمج هندسة المعالم في التثليث للسطح. تشير الخيارات ذات التعيين الثابت أو الناعم إلى ما إذا كانت حواف الميزة تمثل فواصل مميزة في المنحدر أو تغييرًا تدريجيًا.

• نقاط الإرساء - نقاط الارتفاع التي لا تتضاءل أبدًا. هذا الخيار متاح فقط لهندسة المعالم أحادية النقطة.

• خط متشدد أو خط ناعم - خطوط فاصلة تفرض قيمة ارتفاع.

• hardclip أو softclip - مجموعة بيانات مضلعة تحدد حدود مجموعة بيانات LAS.

• hardderase أو softterase - مجموعة بيانات Polygon التي تحدد الثقوب في مجموعة بيانات LAS.

• hardreplace أو softreplace - مجموعة بيانات مضلعة تحدد المناطق ذات الارتفاع الثابت.

5.    Coordinate System (optional) نظام الإحداثيات (اختياري)

The spatial reference of the LAS dataset. If no spatial reference is explicitly assigned, the LAS dataset will use the coordinate system of the first input LAS file. If the input files do not contain any spatial reference information and the Input Coordinate System is not set, then the LAS dataset's coordinate system will be listed as unknown.

المرجع المكاني لمجموعة بيانات LAS. إذا لم يتم تعيين مرجع مكاني بشكل صريح ، فستستخدم مجموعة بيانات LAS النظام الإحداثي لملف LAS للإدخال الأول. إذا كانت ملفات الإدخال لا تحتوي على أي معلومات مرجعية مكانية ولم يتم تعيين نظام تنسيق الإدخال ، فسيتم إدراج النظام الإحداثي لمجموعة بيانات LAS على أنه غير معروف.

6.    Create PRJ For LAS Files (optional) إنشاء بي أر جي لملفات لاس (اختياري)

Specifies whether .prj files will be created for the LAS files referenced by the LAS dataset.

· ALL_FILES—All LAS files will have a corresponding PRJ file.

يحدد ما إذا كان سيتم إنشاء ملفات .prj لملفات LAS المشار إليها بواسطة مجموعة بيانات LAS.

• NO FILES - لن يتم إنشاء ملف PRJ في أي ملفات. هذا هو الافتراضي.

• FILES MISSING_PROJECTION - فقط ملفات LAS التي ليس لها مرجع مكاني سيكون لها ملف PRJ مطابق.

• ALL FILES - ستحتوي جميع ملفات LAS على ملف PRJ مطابق.

7.    Compute Statistics (optional) حساب الإحصائيات (اختياري)

Specifies whether statistics for the LAS files will be computed and a spatial index generated for the LAS dataset. The presence of statistics allows the LAS dataset layer's filtering and symbology options to only show LAS attribute values that exist in the LAS files. A .lasx auxiliary file is created for each LAS file.

· Unchecked—Statistics will not be computed. This is the default.

· Checked—Statistics will be computed.
