What is a pixel and how does it relate to map making?

Why is a computer screen called CRT?
CRT stands for Cathode Ray Tube, This is the way that the image is projected onto the screen. In much the same way as old style TVs and is the reason CRT screens have that big back end (to accomadate the Cathode Ray Tube) This is different from newer Computer Monitors such as TFT screens; Trans reflective.

Identify two types of flat panel monitors and explain their differences?
Two examples of flat panel monitors are Light-emitting diode display (LED) and Liquid-crystal display (LCD). LCD monitors light the entire backside of the LCD panel using a cold compact florescent light while LED monitors use its own light to provide the backlight. LED lights more energy efficient than the cold compact florescent light used by LCD.
What materials are needed to do a green screen project?
To set up a green screen project, also known as chroma keying, you'll need specific materials to achieve a seamless background replacement in post-production. Here's a list of essential materials and equipment for a green screen project: Green Screen Background: Use a green screen backdrop made of chroma key green fabric or paint a wall or background with chroma key green paint. This color is often used because it is distinct from most skin tones and is easily replaced in post-production. Lighting: Proper lighting is crucial for achieving a clean green screen effect. Use soft, even lighting to eliminate shadows and ensure uniform green color. This often involves using key lights, fill lights, and backlights. Be aware of shadows on both the subject and the green screen. Light Stands and Mounting Hardware: Use light stands to support your lighting equipment. Additionally, you may need mounting hardware to position lights at the correct angles and heights. Key Lights: Key lights are the primary lights that illuminate your subject and green screen. They should be positioned to create even and consistent lighting on both. Fill Lights: Fill lights help reduce shadows on the subject. They are typically placed on the opposite side of the key lights. Backlights: Backlights, also known as rim lights, help separate the subject from the green screen by creating a highlight along the edges of the subject. Camera: Use a good-quality camera to capture your footage. A camera with manual settings and good low-light performance is preferable for achieving optimal results. Tripod: A stable tripod is essential to prevent camera movement and ensure consistent framing. Chroma Key Software: You'll need video editing or compositing software that supports chroma keying. Popular options include Adobe Premiere Pro, Final Cut Pro, DaVinci Resolve, and OBS Studio (for live streaming). Computer: A computer with sufficient processing power and memory is necessary to handle the video editing or compositing tasks. Microphones: If you are recording audio with your video, use external microphones to capture high-quality sound. This is particularly important if you're recording dialogue or narration. Green Screen Kits (Optional): You can purchase green screen kits that include the green screen backdrop, stands, and lights. These kits are convenient for those who want an all-in-one solution. Props and Wardrobe: Ensure that the subject's clothing and any props do not contain the same green color as the green screen background. Space: Choose a location with enough space to set up the green screen, lights, and cameras without any restrictions. Remember to pay attention to the lighting setup, as proper lighting is crucial for achieving a successful green screen effect. Additionally, the key is to ensure a uniform and consistent green color on the backdrop for effective background replacement in post-production.
Is a measure of how many spots on a CRT screen are addressable by software?
The total number of spots on a CRT screen that are addressable by software is called screen resolution. Typical resolutions include 1024x768, 800x600 and 1600x1200.
