Interactive web maps give you and your team the opportunity to explore and update data. As you zoom in, additional data and insights become available. Click on the map to discover location-specific data displayed in charts or infographics. Filter data and change the symbology to gain additional perspectives and reveal new patterns.

Use your maps even without a network or cellular connection. Download your maps before you go, and conveniently access them on your smartphone or tablet. Once you are connected again any data you or your team added is automatically synchronized.

Discover and refine your data's story using a set of intuitive analysis tools, such as drive times and buffers. Smart mapping, pioneered by Esri, uses data-driven styling, colors, and symbols to guide your exploration and transform your raw data into useful information. You can also understand your data better by visualizing it with different map styles.

Deepen your understanding and expose relationships by adding authoritative data, such as demographics, imagery, boundaries, and live feeds, to your map. ArcGIS Living Atlas of the World, the most comprehensive collection of global geographic information, is included with every ArcGIS mapping product.

Brand and personalize your maps using custom symbols, colors, and basemaps. Make your data pop by placing it on a historic, creative, or present-day basemap. You can also customize the basemaps or build your own.

Create apps that enable your audience to not only view your map but also interact with the data. Choose from a variety of focused app templates and create an app in just a few clicks. Include them on your website using the convenient embed code. Each app has a specific purpose to help tell your story and keep your audience engaged.

The N.C. Department of Environmental Quality (DEQ) has created a department community mapping system, which will be used to inform some department decisions, such as specific plans for local outreach and public participation.

The Technical Mapping Advisory Council (TMAC) is a federal advisory committee established to review and make recommendations to FEMA on matters related to the national flood mapping program authorized under the Biggert-Waters Flood Insurance Reform Act of 2012.

The national flood mapping program provides flood maps to inform communities about the local flood risk and help set minimum floodplain standards so communities may build safely and resiliently. The Flood Insurance Rate Maps (FIRMs) established under the program help determine the cost of National Flood Insurance Program flood insurance which helps property owners financially protect themselves against flooding.

The TMAC reviews the national flood mapping activities authorized under the law and prepares recommendations for the FEMA Administrator. The TMAC also produces an annual report on the impacts of climate sciences and future conditions and how they may be incorporated into the mapping program. The TMAC is comprised of representatives from federal, state, local and private sector organizations as mandated in the Biggert Waters Reform Act of 2012 and governed by the Federal Advisory Committee Act (FACA) requirements.

The function surface_area_of_cube takes an argument expected tobe an instance of float, as indicated by the type hintedge_length: float. The function is expected to return an instanceof str, as indicated by the -> str hint.

You may still perform all int operations on a variable of type UserId,but the result will always be of type int. This lets you pass in aUserId wherever an int might be expected, but will prevent you fromaccidentally creating a UserId in an invalid way:

Note that these checks are enforced only by the static type checker. At runtime,the statement Derived = NewType('Derived', Base) will make Derived acallable that immediately returns whatever parameter you pass it. That meansthe expression Derived(some_value) does not create a new class or introducemuch overhead beyond that of a regular function call.

Recall that the use of a type alias declares two types to be equivalent toone another. Doing type Alias = Original will make the static type checkertreat Alias as being exactly equivalent to Original in all cases.This is useful when you want to simplify complex type signatures.

In contrast, NewType declares one type to be a subtype of another.Doing Derived = NewType('Derived', Original) will make the static typechecker treat Derived as a subclass of Original, which means avalue of type Original cannot be used in places where a value of typeDerived is expected. This is useful when you want to prevent logicerrors with minimal runtime cost.

The subscription syntax must always be used with exactly two values: theargument list and the return type. The argument list must be a list of types,a ParamSpec, Concatenate, or an ellipsis. The return type mustbe a single type.

Callable cannot express complex signatures such as functions that take avariadic number of arguments, overloaded functions, orfunctions that have keyword-only parameters. However, these signatures can beexpressed by defining a Protocol class with a__call__() method:

Callables which take other callables as arguments may indicate that theirparameter types are dependent on each other using ParamSpec.Additionally, if that callable adds or removes arguments from othercallables, the Concatenate operator may be used. Theytake the form Callable[ParamSpecVariable, ReturnType] andCallable[Concatenate[Arg1Type, Arg2Type, ..., ParamSpecVariable], ReturnType]respectively.

Since type information about objects kept in containers cannot be staticallyinferred in a generic way, many container classes in the standard library supportsubscription to denote the expected types of container elements.

list only accepts one type argument, so a type checker would emit anerror on the y assignment above. Similarly,Mapping only accepts two type arguments: the firstindicates the type of the keys, and the second indicates the type of thevalues.

To denote a tuple which could be of any length, and in which all elements areof the same type T, use tuple[T, ...]. To denote an empty tuple, usetuple[()]. Using plain tuple as an annotation is equivalent to usingtuple[Any, ...]:

Changed in version 3.12: Syntactic support for generics and type aliases is new in version 3.12.Previously, generic classes had to explicitly inherit from Genericor contain a type variable in one of their bases.

Another difference between TypeVar and ParamSpec is that ageneric with only one parameter specification variable will acceptparameter lists in the forms X[[Type1, Type2, ...]] and alsoX[Type1, Type2, ...] for aesthetic reasons. Internally, the latter is convertedto the former, so the following are equivalent:

A user-defined generic class can have ABCs as base classes without a metaclassconflict. Generic metaclasses are not supported. The outcome of parameterizinggenerics is cached, and most types in the typing module are hashable andcomparable for equality.

Notice that no type checking is performed when assigning a value of typeAny to a more precise type. For example, the static type checker didnot report an error when assigning a to s even though s wasdeclared to be of type str and receives an int value atruntime!

That means when the type of a value is object, a type checker willreject almost all operations on it, and assigning it to a variable (or usingit as a return value) of a more specialized type is a type error. For example:

Initially PEP 484 defined the Python static type system as usingnominal subtyping. This means that a class A is allowed wherea class B is expected if and only if A is a subclass of B.

This requirement previously also applied to abstract base classes, such asIterable. The problem with this approach is that a class hadto be explicitly marked to support them, which is unpythonic and unlikewhat one would normally do in idiomatic dynamically typed Python code.For example, this conforms to PEP 484:

PEP 544 allows to solve this problem by allowing users to writethe above code without explicit base classes in the class definition,allowing Bucket to be implicitly considered a subtype of both Sizedand Iterable[int] by static type checkers. This is known asstructural subtyping (or static duck-typing):

Any stringliteral is compatible with LiteralString, as is anotherLiteralString. However, an object typed as just str is not.A string created by composing LiteralString-typed objectsis also acceptable as a LiteralString.

LiteralString is useful for sensitive APIs where arbitrary user-generatedstrings could generate problems. For example, the two cases abovethat generate type checker errors could be vulnerable to an SQLinjection attack.

In general, if something returns self, as in the above examples, youshould use Self as the return annotation. If Foo.return_self wasannotated as returning "Foo", then the type checker would infer theobject returned from SubclassOfFoo.return_self as being of type Foorather than SubclassOfFoo.
