The Choose layer to filter by parameter is the input point, line, or area layer that will be used to filter the first layer.

When you perform spatial aggregation or spatial filtering on data from the same database connection, you must ensure that all the data is stored in the same spatial reference system. For datasets from Microsoft SQL Server, the data must also have the same data type (geography or geometry).

You can use selected features in Spatial Filter. For example, if you have a dataset of store locations across the United States but you only want to analyze stores in California, you can select California in the US States layer, drag the selected feature to the map of store locations, and drop the selected feature on the Filter by selected feature drop zone.

When as a photographer, you shoot for a client, things get a little different. Your getting paid for visually representing a location, item or person accurately.

If a feature in the first layer contains a feature in the second layer, the feature in the first layer is excluded from the output.

These photographs of tall buildings in Toronto will give you some basis as to what I am talking about. Basically, a convex mirror effect is applied because the lens is bending the light, forcing a larger image area to be recorded on a smaller capture service. Or in super confusing mathematical formula format: R=(a* r ^ 3 + b * r ^2 + c + d).

Spatial Filter can be used to create a result dataset that contains a copy of the features on a map that meet a series of criteria based on a spatial query.

See the thing is, as a photographer can shoot anyway you want. Use distortion, or make the shot look crazy. Or make your images look normal it is up to you.

So, it has been 7 years since I originally wrote this post, “5 Tips to Overcome Barrel Distortion”. I would say I am bit wiser, and a little less “this is the way it is!”

Whether it’s an old family photo, a treasured painting, or a vibrant print, adding artwork to your home is one of the most effective ways to make a space feel warm and inviting. But before enjoying your new artwork, you must hang it up!

A city's police department is conducting an analysis to determine if there is a relationship between violent crimes and unemployment rates. An expanded summer job program will be implemented for high schools in areas where there is high violent crime and high unemployment. Spatial Filter can be used to create a dataset of high schools within the remediation areas.

There’s a lot that goes into taking a great photograph. Composition, lighting, and timing all play a role. But one of the most important elements of a great photo is depth of field. In this blog post, we’ll break down what depth of field is and how you can use it to take better photographs.

There is still some relevant information in here regarding the use of wide-angle lenses in photography. As a commercial photographer traveling throughout Canada, I use a lot of different lenses, almost everything.

Motion blur is an interesting effect that can be used in photography to create a sense of motion. It can be used to convey a feeling of speed or to show the motion of objects in a photograph.

SAP HANA does not support ST_Contains for geographic (round-earth) coordinate systems. Spatial filtering using the Contains and Doesn't Contain filter types will fail for SAP HANA datasets with a geographic coordinate system.

If you’re an architect, then you know that the devil is in the details. And when it comes to photography, one of the most important details is perspective.

The Choose layer to filter parameter is the input point, line, or area layer that you want to filter. The result dataset will be a subset of this layer.

If you're a photographer, chances are you've considered renting a photo studio at some point. After all, having your own space where you can control the lighting and environment can be a great way to get the perfect shot. But is it worth it? Let's take a look at the...

In 2018 you can use camera raw to fix and overcome barrel distortion use lens corrections, it is awesome. The software has become so good that barrel distortion is far less of an issue.

I also wrote this other one on how to use a wide angle lens properly. Also check out: What is the Perfect Shutter Speed?

A Fisheye looks good in maybe 1% of the instances you will have the opportunity to use one. It is a specialty lens that is more for dramatic effect.

If a feature in the first layer intersects a feature in the second layer, the feature in the first layer is excluded from the output.

Generally, barrel distortion occurs when a wide-angle lens is used to photograph a subject with strong vertical or horizontal lines. Especially when photographing architecture, it is important that verticals stay straight.

Shooting a panoramic image allows you to use a lens with a longer focal length yet still capture a wide field of view. I will often shoot two or three image pans so I can create the exact image I want without adding distortion.

The Choose type of filter parameter is used to specify the relationship between the two input datasets. The following filter types are available in Insights:

If a feature in the first layer contains a feature in the second layer, the feature in the first layer is included in the output.

If a feature in the first layer intersects a feature in the second layer, the feature in the first layer is included in the output.

When shooting with a wide-angle lens always avoid putting subject matter in the edges of the frame. Barrel distortion increases exponentially as you move away from the centre of the lens. Photographing a group shot with a wide angle well often turn one or two members into a cone head.

We earn our income by making our subjects look good. So, barrel distortion can really mess up your photography, and it can stop a lot of clients from ever hiring you in the first place.

Shooting tall buildings with a wide angle lens is a prime candidate for barrel distortion. Don’t be afraid to leave room around the subject and crop down the image, helping you overcome barrel distortion. © Robert Lowdon

On a 35mm format camera a focal length of 50mm is almost identical to that of the human eye. Coincidentally, what you see is what you get. Furthermore, I strongly believe every person interested in photography should learn on a 50mm lens first before moving on to different lens types. Any lens with a shorter focal length will cause barrel distortion.

Simply, objects closer to the camera appear larger and straight lines are curved and objects in background appear smaller and further away.
