Have you ever worked with hillshade maps and noticed that something just doesn’t look right? Perhaps the shading is too dark, or maybe it’s too light. Whatever the issue may be, chances are you’re dealing with bad hillshade lapakgis. But fear not!

In this blog post, we’ll explore different types of bad hillshade and their pros and cons. More importantly, we’ll provide you with 10 actionable ways to improve your bad hillshading skills so that your maps will shine like never before! So grab a cup of coffee (or tea), sit back, and let’s dive into the world of hillshade lapakgis together.

What is bad hillshade?

Hillshade maps have become a staple in cartography, used to represent terrain relief by simulating the effects of light on the surface. However, not all hillshading is created equal. Bad hillshade refers to shading that does not accurately reflect the real-world topography it intends to represent.

One common issue with bad hillshade is overly dark or light areas that obscure or exaggerate features of interest. Another issue can arise when shadowing and highlighting create unnatural-looking slopes or contours that do not match reality.

Bad hillshade can also occur if you use inappropriate color scales, such as using too many colors for a small area or matching contrasting colors poorly.

The reasons behind bad hillshade vary from data quality issues like incorrect elevation models, raster resolution discrepancies, and other inaccuracies in source data to errors resulting from setting parameters incorrectly during map creation.

To achieve accurate and visually pleasing results in your maps, knowing how to identify and avoid bad hillshading practices is crucial.

The Different Types of Bad Hillshade

When it comes to hillshade maps, not all bad hillshades are created equal.

Here are some of the different types of bad hillshades you may encounter:

1. Over-exaggerated shadows: This occurs when the shadows in your map are too dark and pronounced, making it difficult to distinguish between features.

2. Under-exaggerated shadows: The opposite problem of over-exaggeration is when the shadows on your map are too light or non-existent, making it challenging to discern elevation changes.

3. Inconsistent shadows: This type of bad hillshade happens when there is an inconsistency in how the shadowing appears throughout a map. It can create visual confusion and inaccuracies in terrain representation.

4. Incorrect directionality: If the light source used for creating your hillshade is not accurate, this can result in distorted or unrealistic representations of terrain elevations.

5. Blocky shading: This occurs when there isn’t enough detail included in a raster file that has been resampled at a low resolution resulting in blocky looking shaded relief.

Understanding these various types of bad hillshades will help you diagnose problems with your own maps and work towards improving their quality for better spatial analysis and decision-making purposes.

Pros and Cons of Bad Hillshade

Bad hillshade can have both positive and negative effects on maps. One of the main advantages is that it can be used to highlight certain features or give a more dramatic effect to the map. This technique can be useful for artistic purposes, such as creating an eye-catching backdrop for marketing materials.

However, bad hillshade can also lead to inaccurate maps if not properly executed. It may create false shadows or highlights that could misrepresent actual terrain features and cause confusion among users. Additionally, some people may find bad hillshades visually distracting or difficult to interpret.

Another drawback of bad hillshading is its impact on readability. A poorly-executed hillshade can make text labels difficult to read, particularly when placed over areas with high contrast between light and dark shades.

On the other hand, a well-implemented bad hillshade technique can enhance the overall aesthetic appeal of a map while still maintaining accuracy and readability. By understanding how to balance shading intensity and contrast levels, you can produce effective results that add depth and dimensionality without detracting from important information presented in your map.

There are pros and cons associated with using bad hillshading techniques in mapping applications – hence why it’s crucial for cartographers to consider these factors carefully before implementing them in their work

10 Ways to Improve Bad Hillshade

Bad hillshade can be a frustrating issue for anyone working with maps. It can make important features difficult to see and cause confusion for users. Fortunately, there are several ways to improve bad hillshade and ensure that your maps are clear and easy to read.

One way to improve bad hillshade is by adjusting the brightness and contrast of your map image. This can help bring out important details in the terrain and make it easier to differentiate between different elevations.

Another option is to adjust the sun angle or azimuth used when generating the hillshade layer. Experimenting with different angles can help you find one that works better for your particular map.

You may also want to consider smoothing out any jagged edges or artifacts in the hillshade layer using image processing tools like Photoshop or GIMP. This can help create a more natural-looking representation of the terrain.

Adding shadows or highlights around key features on your map can also draw attention to them and make them stand out more clearly against the surrounding landscape.

In some cases, simply adding labels or annotations over specific areas of interest on your map can help clarify what’s going on in certain locations where hillshading isn’t providing enough detail.

Consider using color ramps that complement rather than clash with each other as well as picking colors carefully so they don’t overpower underlying data layers such as land cover types which could reduce legibility at small scales by introducing unnecessary visual complexity

Always test potential solutions thoroughly before committing them permanently into production use; this will prevent errors being perpetuated throughout future workflows without detection until much later down stream!


Bad hillshade can be a common problem when creating maps but there are various ways to improve it. By understanding the different types of bad hillshade and their pros and cons, you can choose the best method to improve your map’s visualization. Whether it’s by adjusting the shading parameters or using other data sources for better accuracy, these tips will help you create more realistic and visually appealing maps.

Remember that improving your hillshade lapakgis is not just about aesthetics but also about providing accurate information for users. With these tips in mind, you’ll be able to create beautiful and informative maps that effectively communicate spatial data.
