ArcGIS for Desktop 10.2 has a major focus on quality and performance enhancements with more than 600 software issues addressed.ArcGIS10.2软件主要集中于质量和性能的提升，同时解决600多个软件问题。
Support for parallel processing using up to 4 cores, which was new at 10.1 SP1, has been added to several Spatial Analyst tools (see below).使用4核来支持并行处理的，已经作为新的方法加入到几个空间分析工具中。
Geoprocessing against ArcGIS for Server Linux is 25% faster due to file handling optimizations.由于文件操作优化，在Linux服务系统中，ARCGIS的相关处理速度提高25%
Security
Support signing in to the ArcGIS system from any client once, and allowing these credentials to be used across the ArcGIS system. Many customers have been asking us to implement federated security, particularly in ArcGIS Online. Users are able to leverage their own security identity stores, such as Windows Active Directory or LDAP, not only within their firewall, but against ArcGIS Online. For example, credentials can be passed from ArcMap to ArcGIS Online automatically when performing batch geocoding with Esri’s World Geocoding service.支持客户从任意客户端登录到ArcGIS系统，并且可以使用ArcGIS系统的数据。许多客户要求我们针对ArcGIS Online，支持统一的安全性设施，希望可以利用windows活动目录或者LDAP来管理ArcGIS Oline账户，而不仅仅是防火墙。例如，当用ESRI的世界地理编码服务批理处理地理编码时，许可会自动由arcmap发送到arcgis online.
PKI Support:
Two-factor authentication is often mandatory in secure environments. ArcGIS for Desktop 10.2 adds PKI (Public Key Infrastructure) support to satisfy this requirement. PKI typically is a set of hardware, software, people, policies, and procedures used to manage and distribute, digital certificates. Enterprise, Defense and Intelligence customers are examples of PKI users.ArcGIS10.2增加了对PKI的支持，以增强网络的安全性需求。
Standardized SQL Queries:
At 10.2, by default, map and image services do not support database-specific where clauses in queries. This is a security enhancement implemented to prevent ‘injection attacks’, which are malicious code inserted into a SQL statement. Previously no parsing was done of SQL statements; now a server-wide policy is implemented to reject risky SQL statements.默认情况下，ArcGIS10.2地图和影像服务不支持数据库的where语句查询。这是为防止“注入式攻击”的一种安全性增强，即防止插入在sql语句中的恶意代码入侵。最新的服务器具备解析sql语句的功能，以防止危险的sql语句。
Analysis (Geoprocessing)
Conversion:
The ability to import and export Microsoft Excel spreadsheets using the new Excel to Table and Table to Excel tools is new at 10.2. This is a very popular user requirement.增加exellToTable和TableToExcell的工具.

Geostatistical Analyst has a new ArcPy class – GeostatisticalDatasets which can be used to automate the creation of geostatistical layers for many datasets using the same interpolation parameters for each dataset.Geostatistical Analyst增加了一个Arcpy类，可以根据相同的参数对不同数据批量做插值分析
Spatial Statistics has a new Optimized Hot Spot Analysis tool that interrogates data and determines optimal settings. The underlying science is maintained, and users will not need the statistics background assumed by the Hot Spot Analysis tool.Optimized Hot Spot Analysis工具：空间分析提供了一个热点分析工具，主要用于分析数据确定最佳设置，值得强调的是：使用这个工具用户不需要太多的背景知识。
ArcPy and Python:
ArcGIS for Desktop 10.2 installs Python 2.7.3.
ArcGIS桌面10.2安装的是python2.7.3
ArcPy now supports the creation and use of a SQLite workspace using either the native Esri ST_Geometry spatial data type or the SQLite Spatialite spatial type. SQLite workspaces created by ArcPy’s CreateSQLiteDatabase function are accessible as Desktop workspaces and support feature classes, tables, and views.最新的ArcPy可以引用ESRI本地的ST_Geometry的空间数据类型或SQLite的SpatiaLite的空间类型，去创建和使用SQLLite工作空间。通过arcpy的CreateSQLiteDatabase函数创建的SQLite工作空间支持要素类、表以及视图等，并且可以被ArcGIS桌面访问。
New at 10.2 is the CreateGeocodeSDDraft function that makes an .sddraft file suitable for staging new geocoding services with the arcpy.server module.CreateGeocodeSDDraft函数：在ArcGIS10.2中，可以将ArcGISserver使用的新的地理处理服务保存成sddraft文件。
Multiband rasters are now supported by RasterToNumPyArray and NumPyArrayToRaster functions.RasterToNumPyArray和NumPyArrayToRaster函数支持多波段的栅格数据。
Users can create their own Python site-packages. They can extend Geoprocessing with their own custom tools which become as easy to view and use as the installed System tools. An installation executable can be generated from Python's native distribution utility, optionally including internationalized help.可以使用arcpy包创建基础地理处理工具的自定义工具，可以将该工具做可执行的安装包。
3D GIS
Share 3D Scenes:
With ArcGIS 10.2, users can publish ArcScene projects as a 3D Web Scene and share it on ArcGIS Online or embed it in a custom web page. This will allow users to easily share 3D models, analysis results, or design proposals with decision makers and the public. The 3D Web Scenes are based on WebGL technology, so no plug-in is required for most browsers.在ArcGIS10.2中，用户可以将ArcScene保存的文档发布成3D服务，并且可以上传到ArcGIS Online上或潜入在自定义网页中。这将运行用户方便的将三维模型、分析结果、设计建议等共享与决策者或者公众进行共享。在网页上浏览只需要浏览器有webgl插件即可。
Generate rule-driven 3D content:
ArcGIS 10.2 allows 3D Analyst users to embed CityEngine’s modeling power directly within their existing geoprocessingworkflows. Create 3D models – such as buildings, schematic trees, and 3D zoning regulations – directly from within ArcGISusing rule packages authored in CityEngine 2013.加了对Cityengine模型的建立工具。
LiDAR is faster:
Spatial indexes and summary statistics are automatically calculated for LAS data, providing faster access to source LiDAR data. These indexes and metadata are reused even if the LiDAR is referenced by many LAS Datasets and Mosaic Datasets, allowing anyone consuming the data to benefit from the improved performance. The improvements are particularly effective for larger LAS files (e.g. greater than 200 MB) and for organizations that have a central LAS repository that is exposed on a network.为了提高LIDAR数据的访问效率，会自动计算空间索引和统计数据。即使lidar数据被其他数据集多次引用，他们的元数据仍然可以被重复利用，以增加他们的访问效率。这个增强对于大数据流LAS文件和管理网络上的LAS数据是特别有效的。
ArcGIS for 3D Cities:
The ArcGIS for 3D Cities solution helps users plan and understand their city, by providing the foundation for managing, visualizing, analyzing, and sharing 3D urban spaces. It organizes all city data – such as buildings, zoning regulations, facilities, and city-managed assets, like trees and street lights, into a well-defined information model. It comes with a set of specialized tools and workflows that take advantage of powerful new 3D geoprocessing tools in ArcGIS 10.2 for content creation and 3D urban analysis such as visual impact.ArcGIS 3D解决方案，通过对城市空间数据的管理、组织、可视化等进行分析，帮助客户认知和了解他们的城市。它通过组织建筑物，城市设施，城市管理资产如树和路灯等所有城市数据，将其转化为清晰的信息模型。
上述操作因一整套专业工具和工作流程而实现，而它们得益于ArcGIS10.2系统中强大的新3D地理处理工具--创造模型和分析3D城市数据如视觉效果。
3D Analyst:
In addition to sharing the enhanced Visibility tool with Spatial Analyst, 3D Analyst adds the new Intervisibility tool. This tool determines if sight lines are obstructed by any intermediate features, adding a field that flags if the 3D sight line is obstructed.除了增强的可视化工具与空间分析，三维分析增加了新的通视工具。
该工具用于标识视线是否被中间物阻挡，如果阻挡，会增加一个字段进行标识。
