How to open a .LAS file? How to convert LAS file to PDF file Page Last updated.

What kind of file is this - LAS?

The file format with the .LAS extension contains LIDAR (Detection and Ranging) data stored in binary format. This format is the result of efforts to standardize LIDAR data formats undertaken by ASPRS (American Society for Photogrammetry and Remote Sensing). This format greatly simplifies the exchange of information between suppliers and recipients. The introduction of the LAS format has simplified the inherent complexities of LIDAR data.

The LAS format stores data collected by light sensors. These sensors illuminate the target with laser light and measure the reflected and scattered light to create a three-dimensional image of the target object. This method is commonly used to create accurate maps of an area.

How to open LAS files

If a situation arises in which you cannot open the LAS file on your computer, there may be several reasons. The first and at the same time the most important (it occurs most often) is the absence of an appropriate application serving LAS among those installed on your computer.

The easiest way to solve this problem is to find and download the appropriate application. The first part of the task has already been completed - programs for servicing the LAS file can be found below. Now you just need to download and install the appropriate application.

In the remainder of this page, you will find other possible reasons causing problems with LAS files.

Possible problems with files in the LAS format

The inability to open and work with the LAS file should not mean at all that we do not have the appropriate software installed on our computer. There may be other problems that also block our ability to work with the LIDAR Data Exchange Format file. Below is a list of possible problems.

Corruption of a LAS file which is being opened.
Incorrect LAS file associations in registry entries.
Accidental deletion of the LAS extension description from the Windows registry
Incomplete installation of an application that supports the LAS format
The LAS file which is being opened is infected with an undesirable malware.
There is too little space on your computer to open the LAS file.
Drivers of the equipment used by the computer to open a LAS file are out of date.

If you are sure that all of the above reasons do not exist in your case (or have already been excluded), the LAS file should work with your programs without any problems. If the problem with the LAS file is still not resolved, this may mean that in this case there is another, rare problem with the LAS file. In this case, the only thing left is the help of a specialist.

How to associate a file with an installed program?

If you want to associate a file with a new program (eg moj-plik.LAS) you have two options. The first and the easiest one is to right-click on the selected LAS file. From the open menu, select the option Select default program", then option "Revise" and find the required program. The entire operation must be confirmed by pressing the OK button.

Is there a universal method for opening unknown files?

Many files contain data in the form of text or numbers. It is possible that while opening unknown files (e.g. LAS), a simple text editor popular in Windows, which is Notatnik will allow us to see part of the data encoded in the file. This method allows you to view the contents of many files, but not in the same form as the program designed to serve them.

Install PDF24 Creator
Open the .las file with a reader that can open the file.
Print the file on a virtual PDF24 PDF printer.
The PDF24 Assistant opens a window in which you can save the new file as a PDF, send it by email, fax, or edit it.

What else could cause problems?

There may be more reasons why you cannot open the LAS file (not just the lack of an appropriate application).
Firstly- the LAS file may be incorrectly linked (incompatible) with the installed application to support it. In this case, you need to change this connection yourself. To do this, right-click on the LAS file that you want to edit, click the option "To open with" and then select the program you installed from the list. After this action, problems with opening the LAS file should completely disappear.
Secondly- the file you want to open may simply be damaged. In this case, it would be best to find a new version of it, or download it again from the same source (perhaps for some reason in the previous session the download of the LAS file did not finish and it could not be opened correctly).

Sometimes an error may occur as a result incorrect software installation, which may be due to a problem encountered during the installation process. This may interfere with your operating system link your LAS file to the correct application tool, influencing the so-called "file extension associations".

Sometimes simple reinstalling ESRI ArcGIS for Desktop may solve your problem by properly linking LAS to ESRI ArcGIS for Desktop. In other cases, problems with file associations may result from bad software programming developer and you may need to contact the developer for further assistance.

Advice: Try updating ESRI ArcGIS for Desktop to the latest version to ensure you have the latest patches and updates.

This may seem too obvious, but often The LAS file itself may be causing the problem. If you received a file via an email attachment or downloaded it from a website and the download process was interrupted (such as a power outage or other reason), the file may become damaged. If possible, try getting a new copy of the LAS file and try opening it again.

Carefully: A damaged file can cause collateral damage to previous or existing malware on your PC, so it is important to keep your computer up-to-date with an up-to-date antivirus.

If your LAS file related to the hardware on your computer to open the file you may need update device drivers associated with this equipment.

This problem usually associated with media file types, which depend on successfully opening the hardware inside the computer, e.g. sound card or video card. For example, if you are trying to open an audio file but cannot open it, you may need to update sound card drivers.

Advice: If when you try to open a LAS file you receive .SYS file error message, the problem could probably be associated with corrupted or outdated device drivers that need to be updated. This process can be made easier by using driver update software such as DriverDoc.

If the steps do not solve the problem and you are still having problems opening LAS files, this could be due to lack of available system resources. Some versions of LAS files may require a significant amount of resources (e.g. memory/RAM, processing power) to properly open on your computer. This problem is quite common if you are using fairly old computer hardware and at the same time a much newer operating system.

This problem can occur when the computer is having difficulty keeping up with a task because the operating system (and other services running in the background) may consume too many resources to open LAS file. Try closing all applications on your PC before opening LIDAR Data Exchange File. Freeing up all available resources on your computer will provide the best conditions for attempting to open the LAS file.

If you completed all the steps described above and your LAS file still won't open, you may need to run equipment update. In most cases, even when using older versions of hardware, the processing power can still be more than sufficient for most user applications (unless you're doing a lot of CPU-intensive work, such as 3D rendering, financial/scientific modeling, or intensive multimedia work) . Thus, it is likely that your computer does not have enough memory(commonly called "RAM" or random access memory) to perform the task of opening a file.

Try refreshing your memory to see if this will help you open the LAS file. Today, memory upgrades are quite affordable and very easy to install, even for the average computer user. As a bonus, you you'll probably see a nice performance boost while your computer performs other tasks.
