Convert LAN to HPG

Online GIS converters cap file size and need an upload. reaConverter converts LAN to HPG locally, whatever the size of the dataset.

Online converters too slow for your LAN files? reaConverter works locally and handles unlimited batches. All processing runs locally on your PC, so your files stay private and secure. No command line and no scripting, unlike the usual ogr2ogr route.

Technical note

How LAN and HPG differ in practice

Geospatial coordinates are absolute positions on the earth, and they are large: a projected easting runs to six or seven digits, while latitude and longitude are small decimals. HPG expects a drawing laid out near its own origin in millimetres or inches. The geometry itself converts correctly, but it can land tens of kilometres from 0,0, or arrive at a scale where an entire county is forty units across. Zoom to extents first, then measure one known distance before dimensioning anything. A line in an LAN image is several pixels wide, so tracing it can mean different things and the mode is yours to choose. Centreline returns a single line running down the middle of each stroke, which is what a scanned drawing needs: one entity per line, snappable and dimensionable, rather than a long thin rectangle around it. Outline follows both edges and returns closed shapes, which suits clipart, logos and anything that will be filled or cut. A precision setting controls how closely the traced paths follow the pixel edges. One thing to plan for: vectorised output from this path is black and white, so colour in the LAN does not survive as colour in the HPG.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as HPG opens on any computer and any phone. reaConverter produces those from LAN in batch, entirely offline.

  • Render every file in a folder to HPG with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

Working in a print studio means constantly juggling obscure file formats. I used to waste hours Googling converters or installing random software — until reaConverter became my Swiss Army knife. Install it once, and you're set forever. No internet? No problem!

FAQ

LAN to HPG Conversion

What are LAN files?

LAN is a multiband raster image format of ERDAS, used by the 7.x generation of the ERDAS image processing software, which was later replaced by ERDAS IMAGINE and its .img format. It became widely known as the format for Landsat Thematic Mapper satellite scenes, in which the same area is recorded in several spectral bands, such as visible light and infrared. A file of this type contains all the bands of a scene together, preceded by a short header with the image size and other basic information. The format was widely used in remote sensing, forestry, and land-use mapping, and many programs can still read it today. Its sibling, the .gis format, holds a single band of classified data, such as a land cover map.

What are HPG files?

HPG is a vector image format created in a standard programming language called HPGL (Hewlett-Packard graphics language). Other extensions created in this language include PLT, HP2 and PL2. All are called "plotter files" and are created by drawing programs such as AutoCAD to be printed using a device specialized in vector graphics. An HPG file uses a line series of two-letter codes to render an image and can also include parameters.

Can reaConverter convert LAN to HPG?

Yes! reaConverter instantly converts .lan to .hpg with perfect quality preservation. With its batch processing feature, you can convert multiple files at once in just a few clicks. You can even convert images directly from Windows Explorer using the right-click menu — fast and convenient.

What is reaConverter used for?

reaConverter is a Windows converter for 800+ formats, GIS data among them. For LAN to HPG it replaces the usual detour through QGIS, ArcGIS or ogr2ogr: add the files, pick the output format, and the whole batch converts offline. Surveyors, planners and engineering teams use it to pass data between GIS, CAD and everyday document formats.

Why choose offline conversion with reaConverter?
