Not all areas on satellite images are covered in the same resolution; less populated areas usually get less detail. Some areas may be obscured by patches of clouds.
With the introduction of an easily pannable and searchable mapping and satellite imagery tool, Google's mapping engine prompted a surge of interest in satellite imagery. Sites were established which feature satellite images of interesting natural and man-made landmarks, including such novelties as "large type" writing visible in the imagery, as well as famous stadia and unique geological formations.
Although Google uses the word satellite, most of the high-resolution imagery of cities is

In 2006, Google introduced a Java application called Google Maps for Mobile, intended to run on any Java-based phone or mobile device. Many of the web-based site's features are provided in the application.
On November 28, 2007, Google Maps for Mobile 2.0 was released. It introduced a GPS-like location service that does not require a GPS receiver. The "my location" feature works by utilizing the GPS location of the mobile device, if it is available. This information is supplemented by the software determining the nearest

s. The software then looks up the location of the cell site using a database of known wireless networks and cell sites. The Cell-site location method is used by triangulating the different signal strengths from different cell transmitters and then using their location property (retrieved from the online cell site database) to aid My Location in determining the user's current location. Wireless network location method is calculated by discovering the nearby WiFi hotspots and using their location property (retrieved from the online WiFi database, in the same way as the cell site database) to further discover the user's location.
The order in which these take precedence is:
- GPS-based services
- WLAN-, WiFi-based services
- Cell transmitter-based services
The software plots the streets in blue that are available with a yellow icon and a green circle around the estimated range of the cell site based on the transmitter's rated power (among other variables). The estimate is refined using the strength of the cell phone signal to estimate how close to the cell site the mobile device is.

Cell phones are being increasingly used for navigation assistance. Google Maps Navigation for Android 2.0 is free.
Features provided in the application:
- Search in plain English
- Search by voice
- Traffic view

- Satellite view
- Street View
- Car dock mode
Impact
Google Maps Navigation is free. A potential drawback of Google Maps for Android is that maps are not included in the application file. An internet connection is required to get maps and related information from Google Maps, just like with iPhone’s Google Maps application. This drawback is mitigated by an automatic map caching feature which temporarily stores recently-viewed areas. There is also a 'Download Map Area' feature in the Labs section of Google Maps. The 'Download Map Area' feature enables the user to download the road map and landmark data for an area of 10 square miles (25.9 km²) around any point. The user can do this action multiple times to cover as much area as desired. Google suggests that users can make use of this feature to download the map of a foreign city before traveling to visit it, so that once the user arrives in the city, they can refer to the pre-downloaded road map without needing to use expensive international roaming data. However, the downloaded map area only includes the basic road map and its landmark labels. Google notes that even after you download a map area, "you still need a data connection to see satellite view and 3D buildings, search for Places and get directions."
Google Maps parameters
In Google Maps, URL parameters are sometimes data-driven in their limits and the user interface presented by the web may or may not reflect those limits. In particular, the zoom level (denoted by the z parameter) supported varies. In less populated regions, the supported zoom levels might stop at around 18. In earlier versions of the API, specifying these higher values might result in no image being displayed. In Western cities, the supported zoom level generally stops at about 20. In some isolated cases, the data supports up to 23 or greater, as in

, Africa. Different versions of the API and web interfaces may or may not fully support these higher levels.
As of October 2010, the Google map viewer updates its zoom bar to allow the user to zoom all the way when centered over areas that support higher zoom levels.

The coverage of Google Transit is publicly available. It is spread worldwide, in hundreds of cities and sometimes in entire countries such as China, Japan, Switzerland. The coverage of major cities in the United States and in Canada is almost exhaustive.
In some areas, such as the United Kingdom, Google Transit covers only part of the transit agencies.
In other areas, Google Transit does not provide public transit directions, but still provides the Transit Layer which overlays the schematic of the transit lines on the map. Notable examples include Paris, Berlin, Mexico City and many other capitals around the world.

This service is available in the US and Canada, and is in beta testing in some other countries such as Singapore.
Google My Maps
In April 2007, My Maps was a new feature added to Google's local search maps. My Maps lets users and businesses create their own map by positioning markers, polylines and polygons onto a map. The interface is a straightforward overlay on the map. A set of eighty-four pre-designed markers is available, ranging from bars and restaurants to webcam and earthquake symbols. Polyline and Polygon color, width and opacity are selectable. Maps modified using My Maps can be saved for later viewing and made public or marked as unlisted, in which case a user will need the saved URL with a 42 character unique ID.
Each element added to a My Map has an editable tag. This tag can contain text, rich text or HTML. Embeddable video and other content can be included within the HTML tag.
Upon the launch of My Maps there was no facility to embed the created maps into a webpage or blog. A few independent websites have now produced tools to let users embed maps and add further functionality to their maps. This has been resolved with version 2.78.

Maps data
Google Maps has difficulty processing road data when dealing with cross-boundary situations. For example, users are unable to obtain a route from Hong Kong to Shenzhen via Shatoujiao, because Google Maps does not display and plan the road map of two overlapping places.
Sometimes the names of geographical locations are inaccurate. An example of this type of error may be found in Google Maps

Business listings
Google collates business listings from multiple on-line and off-line sources. To reduce duplication in the index, Google's algorithm combines listings automatically based on address, phone number, or geocode, but sometimes information for separate businesses will be inadvertently merged with each other, resulting in listings inaccurately incorporating elements from multiple businesses.
Google has also recruited volunteers to check and correct ground truth data.
Imagery
Street map overlays, in some areas, may not match up precisely with the corresponding satellite images. The street data may be entirely erroneous, or simply out of date: "The biggest challenge is the currency of data, the authenticity of data," said Google Earth representative

Different domains
There are some differences in frontier alignments between Google Ditu and Google Maps.

However, Google Ditu shows the Chinese frontier strictly according to Chinese claims with no dotted lines indicating the border with India and Pakistan. For example, the

There are some differences between ditu.google.cn and ditu.google.com. For example, the former does not feature My Maps. On the other hand, while the former displays virtually all text in Chinese, the latter displays most text (user-selectable real text as well as those on map) in English. This behavior of displaying English text is not consistent but intermittent – sometimes it is in English, sometimes it is in Chinese. The criteria for choosing which language is displayed is not known.

. The discrepancy is meaningless at the global scale but causes maps of local areas to deviate slightly from true
ellipsoidal Mercator maps at the same scale.
Because the Mercator projects the poles at infinity, Google Maps cannot show the poles. Instead it cuts off coverage at 85° north and south. This is not considered a limitation, given the purpose of the service. There are no roads at those latitudes.
